Wheels are the parts of the vehicle that are under the most demand, yet are also the most underestimated. Wheels are very important because the narrow contact surfaces of the tires are the only contact that the vehicle has with the road.
The tire and rim combinations approved by Volkswagen are specifically designed for each other.
The service life of the tire depends on the tire pressure, the driving style, the way the tires are handled, and correct mounting of the tire.
Rims, tires and wheel bolts
Rims, tires, and wheel bolts are determined based on the vehicle model. Whenever another rim is installed, the wheel bolts to be used must have the correct length and bolt head shape. This ensures that the brakes can work correctly and that the vehicle drives smoothly and safely. For technical reasons, standard rims from other vehicles cannot be used. Under certain circumstances, this may even apply to rims for the same vehicle model. You must consult a suitably qualified professional to replace rim/tire combinations. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
The correct wheel bolts must always be used for each vehicle model, and these bolts must always be tightened to the correct torque ⇒ Monitoring the tightening torque.
WARNING
Incorrect handling of wheels can reduce driving safety and cause serious accidents and fatal injuries.
WARNING
New tires or tires that are old, worn, or damaged cannot provide the maximum vehicle control and braking effect.
This can cause accidents and fatal injuries.
WARNING
If the wheel bolts are not tightened enough to meet the specification, the wheel bolts and consequently the wheel could come loose while driving. Exceeding the tightening specification could damage the wheel bolts and threads.
Wheel bolts that are tightened incorrectly or missing could cause you to lose control of the vehicle and lead to serious accidents and fatal injuries.
WARNING
Improper installation of the tires on the rim can result in damage to the rim and cause tires to suddenly lose air or go flat while driving.
This can cause accidents and fatal injuries.
Handling tires
Preventing damage to the tires
WARNING
Corrosive fluids and materials can cause visible and invisible damage to the tires, which can cause the tires to fail.
This can cause accidents and fatal injuries.
Storing tires
Tires that are more than six years old
Tires age due to physical and chemical processes that affect their function. Tires that have been stored and unused for long periods of time age more quickly than tires that are used continuously.
Volkswagen recommends replacing tires that are more than six years old with new tires. This even applies to tires that may appear to be usable and whose tread depth is still greater than the minimum requirement ⇒ .
Winter and all season tires lose their characteristics to a large extent due to aging, regardless of the remaining tread depth.
The age of the tire can be determined based on the production date ⇒ Tire labeling and tire classifications.
WARNING
Old tires can suddenly lose air or rupture, particularly at high speeds.
This can cause accidents and fatal injuries.
New tires
WARNING
New tires must be broken in because they have reduced traction and braking efficiency when they are new.
This could cause you to lose control of the vehicle and lead to serious accidents and fatal injuries.
The size specifications for new tires may vary significantly from the actual tire dimensions for different tire brands.
Replacing tires
Volkswagen Genuine tires
At the factory, the vehicle can be equipped with Volkswagen Genuine tires. These tires are marked with the symbol and are specially adapted for this vehicle. Volkswagen Genuine tires fulfill the highest standards of safety and driving characteristics when used appropriately.
Recalibrating the Tire Pressure Monitoring System
The Tire Pressure Monitoring System must be recalibrated each time one or more wheels is replaced. This also applies if the tires are rotated, for example from front to back ⇒ How the Tire Pressure Monitoring System Works.
WARNING
Wheels must have enough clearance from vehicle components. If there is not enough clearance, tires could rub against components of the suspension, the body, and the brake lines.
This may cause the brake system to fail, the tread to separate, and the tire to rupture, resulting in serious accidents and fatal injuries.
WARNING
Dirt can damage the valves and introduce leaks, causing the tire to lose air.
If the tire pressure is too low, the tire can heat up so much while driving that the tread separates or the tire ruptures, which in turn can lead to serious accidents and/or fatal injuries.
NOTICE
Driving over potholes and curbs can cause the tires to become deformed.
Damage to the tires and rims can result.
NOTICE
The valves may be damaged by dirt.
NOTICE
The valves can be damaged when replacing wheels.
Always dispose of old tires correctly and according to regulations.
If the spare wheel is different from the regular vehicle wheels, e.g. in the case of winter tires or a temporary spare wheel, only use the spare wheel temporarily and in the event of a breakdown, and drive especially carefully. Replace the compact spare wheel with a regular wheel as soon as possible.
Using tires approved by Volkswagen ensures that the dimensions will fit correctly on your vehicle. If other tires are used, the seller must provide a certificate from the tire manufacturer stating that the tires are suitable for the vehicle. Keep the certificate stored safely in the vehicle.
Handling rims
Preventing damage to the rims
Rims with bolted rim ring or accent elements
Rims with a bolted rim ring or accent element consist of multiple pieces. These pieces are connected together with special bolts. Damaged rims must be replaced and may only be repaired by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Rim identification
In some countries, new rims must include information about certain properties. The following information may be on the rim:
WARNING
Using unsuitable or damaged rims can impair driving safety and cause accidents and serious injuries.
WARNING
Loosening and tightening bolts incorrectly on rims with bolted rim rings can cause severe accidents and death.
Incorrect tire pressures negatively affect vehicle handling and can cause increased tire wear or even a flat tire ⇒ . Above all, the correct tire pressure is especially important when driving at high speeds.
Fig. 175 On the driver door pillar: Tire inflation pressure label
The tire inflation pressure label indicates the correct tire inflation pressure for approved tires and is located on the driver door pillar fig. 175. The factory-installed tires can be winter, summer or all-season tires.
An incorrect tire pressure can cause increased tire wear, negatively affect driving behavior and damage tires. Compliance with the correct tire pressure is very important, particularly when driving at high speeds.
The specified tire pressure is given for a cold tire. For warm tires, the pressure is higher.
Never reduce the pressure of a warm tire in order to reach the specified value. This will cause the actual pressure when the tire is cold to be too low.
WARNING
A tire pressure that is too low can result in a sudden loss of air, separation of the tire tread or bursting of the tire while driving. An incorrect tire pressure shortens the service life of the tire and negatively affects driving behavior.
An incorrect tire pressure can cause accidents and fatal injuries.
WARNING
Excessive speeds and vehicle overloading can cause overheating, sudden tire damage (including tire blow-outs) and separation of the tread.
This can cause accidents and fatal injuries.
NOTICE
Careless handling of the tire pressure gage may damage the valve.
Tire pressures that are too low increase fuel consumption.
Tire inflation pressure for cold tires
Vehicles Approved as Light Commercial Vehicles
Details of the correct tire pressure are located on the tire pressure label on the driver's door pillar. If the details on the tire pressure label differ from the details in the Manual, the details on the tire pressure label apply.
2) This data was not yet available at the time of printing.
The correct wheel bolts must always be used for each vehicle model, and these bolts must always be tightened to the correct torque. The wheel bolt tightening torque must be checked regularly with a functional torque wrench. In addition, the tightening torque must be checked immediately after each wheel change with a functional torque wrench. If the wheel bolts are not tightened enough to meet the specification, the wheel bolts and consequently the wheel could come loose while driving.
Exceeding the tightening specification could damage the wheel bolts and threads.
Wheel bolts that are corroded and difficult to turn must be replaced and the threads in the wheel hub must be cleaned before checking the tightening torque. Never grease or oil the wheel bolts and the threads in the wheel hub.
Wheel bolt tightening specification
The tightening torque of the wheel bolts is specified in the chapter on replacing wheels → page, Changing a wheel.
WARNING
If the wheel bolts are not tightened enough to meet the specification, the wheel bolts and consequently the wheel could come loose while driving. Exceeding the tightening specification could damage the wheel bolts and threads.
Wheel bolts that are tightened incorrectly or missing could cause you to lose control of the vehicle and lead to serious accidents and fatal injuries.
Replacing tires
Fig. 176 Diagram for rotating the wheels (general example).
To ensure that the tires wear evenly, rotating the tires regularly according to the diagram is recommended fig. 176. This will allow the tires to have approximately the same length of service life.
Volkswagen recommends having the wheel replacement carried out by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Tread depth
Most driving situations require a tire tread that is as deep as possible. All tires, or at least tires on the same axle, must have an even tread depth ⇒ . This applies in particular to wet or wintry road conditions.
In most countries, the legal minimum tread depth is 1.6 mm (1/16 of an inch). This is measured in the tread grooves next to the wear indicators. Observe any legal regulations specific to the country where you are driving.
Note the legal requirements in the applicable country for minimum tread depths on winter and all-season tires.
Tire wear
Tire wear depends on various factors:
An imbalance can occur while driving, which can be noticed by uneven steering. Tire imbalances also affect tire wear. In these situations, have the wheels balanced again.
Incorrect wheel alignment impairs driving safety and increases tire wear. If there is high degree of tire wear, have the wheel alignment checked by an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Tire Wear when Driving with a Sporty Driving Style
Driving quickly around curves, rapid acceleration, and heavy braking increase tire wear.
If you drive with a sporty driving style, check the tread depth every 5000 to 10,000 km (approx. 3107 to 6214 miles).
Tread wear indicator in tires
Fig. 177 In the tread grooves: wear indicator.
The tread wear indicator is 1.6 mm (1/16 in) above the base of the tread fig. 177. Markings on the sides of the tire indicate the location of the tread wear indicator fig. 177.
The tread wear indicator indicates if a tire is worn out. At the latest, the tire must be replaced if the tread depth is worn down to the tread wear indicator.
When you check the tread depth, you must check the wear indicators of all tread grooves.
WARNING
Worn tires are a safety risk and make it difficult to control the vehicle well. They increase the braking distance and the risk of skidding.
Worn tires have significantly less grip. Particularly on wet roads, the vehicle is more likely to "hydroplane".
Worn tires could cause loss of vehicle control, serious accidents and death.
Winter tires
Summer tires offer very little holding force on icy or snowy roads. Winter or all-season tires improve vehicle handling and braking performance in winter road conditions. Volkswagen recommends using winter tires on the vehicle at temperatures below +7 ºC (+45 ºF) or in winter road conditions. This also applies to vehicles with all-wheel drive (4MOTION).
The effectiveness of winter tires or all-season tires is greatly reduced when the tire tread is worn down to a depth of 4 mm (approx. 5/32 in).
The following applies when using winter tires:
Speed restriction
Winter tires have a speed restriction based on their speed rating ⇒ Tire labeling and tire classifications.
A speed warning can be set in the Vehicle settings menu in the Infotainment System under the Tires menu.
On V winter tires, the speed restriction and required tire pressure depend on the engine. Always ask an authorized Volkswagen dealer or authorized Volkswagen Service Facility about the permitted speed and required tire pressure.
Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
WARNING
In winter road conditions, do not let the improved driving characteristics of winter tires tempt you to take safety risks, as otherwise you may lose control of the vehicle, resulting in serious injuries.
When temperatures are above +7 ºC (+45 ºF), summer tires provide better vehicle handling. There is less road noise, the tires wear more slowly, and economy is better.
For vehicles with a Tire Pressure Monitoring System, the system must be recalibrated after changing to winter tires ⇒ How the Tire Pressure Monitoring System Works.
The speed limit and tire load of winter tires may differ from those of summer tires.
You can contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for permitted winter tire sizes. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Snow chains
Note the legal requirements and the permitted maximum speed when driving with snow chains.
Snow chains improve driving and braking handling when on roads covered with ice or snow.
Snow chains may only be mounted on the front wheels and only on the following tire/rim combinations:
If possible, use fine-mesh snow chains that include a chain lock no larger than 11 mm (approx. 7/16 in).
Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility for more information about wheel, tire, and snow chain sizes. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Snow chains may only be used on tire/rim combinations that are approved for snow chain operation.
If using snow chains, remove the wheel covers and rim accent rings before mounting the snow chains. However, the wheel bolts must be covered with caps for safety reasons. Caps can be obtained from an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Using snow chains on the compact spare tire or collapsible spare tire
Using snow chains on the compact spare tire or collapsible spare tire is not permitted for technical reasons.
1. If a front tire is flat, mount the compact spare tire or collapsible spare tire on the rear axle.
2. Replace the damaged front wheel with the removed rear wheel. Pay attention to the running direction when doing this.
Volkswagen recommends attaching the snow chains before mounting the wheel.
WARNING
Using unsuitable snow chains or installing snow chains incorrectly can cause serious accidents and death.
NOTICE
If snow chains are used on routes that are not snowy, they will impair the driving characteristics, damage the tires, and be quickly destroyed.
NOTICE
Snow chains that come into contact with the rim directly can scratch or damage the rim.
On vehicles with a Tire Pressure Monitoring System, the system must be reprogrammed after snow chains are mounted ⇒ How the Tire Pressure Monitoring System Works.
Damage to tires and rims can often occur where it is not visible ⇒ .
If you suspect that a wheel is damaged, slow down and stop as soon as traffic allows and it is safe to do so.
Vehicle pulls to one side or unusual vibrations
The vehicle pulls to the left or right when driving, or there are unusual vibrations. This could indicate tire damage or too low a tire inflation pressure.
Check the tires! Slow down immediately and stop the vehicle as soon as the traffic situation allows and it is safe to do so.
1. Check the tires and rims for damage.
2. Do not continue driving if there is tire damage.
3. Replace the damaged wheel ⇒ Introduction. If necessary, contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.
4. If no exterior damage is visible, drive slowly and carefully to the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility to have the vehicle checked. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Foreign object stuck in the tire
A foreign object is stuck in the tire or between the tread segments.
1. If an object has punctured through to the inside of a tire, leave the object in place. Objects stuck between the tire tread segments can be removed.
2. Replace the damaged wheel ⇒ Introduction. If necessary, contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance.
3. Check and adjust the tire pressure.
4. Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Tires lose traction
The vehicle loses traction when driving along curved stretches, and swerves. The braking distance is longer and the anti-slip regulation (ASR) and the anti-lock brake system (ABS) take control earlier.
The tire may be too worn down to guarantee sufficient traction ⇒ Monitoring the tread depth.
1. Go slowly and carefully to the nearest suitably qualified professional to have the vehicle checked. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
Wheel bolts can only be undone with difficulty
Wheel bolts can corrode over time. This means that the wheel bolts can only be undone with difficulty.
1. Contact professional assistance, or drive slowly and carefully to the nearest qualified professional to have the vehicle checked. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
WARNING
Unusual vibrations or the vehicle pulling to one side while driving may indicate tire damage.
Tire damage could cause loss of vehicle control, accidents and serious or fatal injuries.
The Tire Pressure Monitoring System warns the driver if tire pressures are too low.
The Tire Pressure Monitoring System uses the ABS sensors to monitor the RPM and therefore the rolling circumference of the individual wheels during travel.
If a tire loses air or the tire pressure is too low, the rolling circumference is reduced and the RPM increases.
The Tire Pressure Monitoring System shows a change in the rolling circumference of the tires via the indicator light in the instrument cluster.
The following situations can also cause the RPM to change:
The Tire Pressure Monitoring System will not work if the ESC or ABS is malfunctioning ⇒ Troubleshooting.
Reference Pressure
The reference pressure for the Tire Pressure Monitoring System is the recommended tire pressure for the tires installed at the factory when the tires are cold at maximum load. The reference pressure corresponds to the details on the tire pressure label ⇒ Checking the tire pressure.
If the tire pressure has been correctly adjusted on all four tires, the Tire Pressure Monitoring System must be re-calibrated ⇒ Calibrating the Tire Pressure Monitoring System. This adapts the reference pressure to the current tire pressure.
The Tire Pressure Monitoring System may not react at first or may not react at all when you are driving in a sporty manner, or on snow-covered or unpaved roads, when you are driving with snow chains, or in certain other situations. A change in the tread circumference of a tire is signaled by the Tire Pressure Monitoring System indicator in the instrument cluster (telltale).
The tire pressure recommended for the tires originally installed on the vehicle is on a sticker on the driver door jamb.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
WARNING
The Tire Pressure Monitoring System is not a replacement for the driver's attention and works only within the system limitations. The Tire Pressure Monitoring System cannot detect all driving situations and may not react, or may react with a delay, or may react in a way that is not desired. If you are careless, there is a risk of accidents, serious injuries and death.
WARNING
If you drive with insufficient tire pressure, the tire could become so hot that the tread could separate, the tire could rupture, and you could lose control of the vehicle.
Tire pressure that is too high or too low shortens the service life of the tire and affects driving behavior.
Different tire pressures or low tire pressures can increase tire wear, decrease vehicle stability, increase braking distance, and result in tire damage, tire failure and loss of vehicle control.
This can cause serious accidents and fatal injuries.
WARNING
Excessive speeds and vehicle overloading can cause overheating, sudden tire damage (including tire blow-outs) and separation of the tread.
This can cause accidents and fatal injuries.
Low tire pressure increases fuel consumption and tire wear.
New tires may expand slightly the first time they are driven at high speeds, which can trigger a tire pressure warning.
Only replace old tires with tires that have been approved by Volkswagen for the vehicle model.
Do not rely on the Tire Pressure Monitoring System alone. Inspect the tires regularly to make sure the tire pressure is correct and check the tires for any signs of damage, such as punctures. Remove any objects stuck in the tire tread as long as they have not punctured the inside of the tire.
Regular Maintenance
The Tire Pressure Monitoring System is not intended to replace regular inspection and maintenance of the tires. The driver is responsible for ensuring that the correct tire pressure is used at all times, even if the Tire Pressure Monitoring System is not showing a warning that the tire pressure is too low.
The tire pressure of all tires must be checked once a month when the tires are cold and must correspond to the vehicle manufacturer's specifications on the tire inflation pressure label.
This also applies to the tire pressure of the spare wheel or compact spare wheel.
The recommended tire pressure for the tires installed at the factory is specified on the tire inflation pressure label ⇒ Checking the tire pressure.
Unresolved Malfunctions
If the Tire Pressure Monitoring System displays a malfunction, the tire pressure cannot be monitored correctly. A malfunction in the Tire Pressure Monitoring System can have a number of causes, e.g. a wheel or a tire being replaced. After replacing a wheel or tire, you must check whether the indicator light displays a system malfunction to make sure that the Tire Pressure Monitoring System is working properly ⇒ Troubleshooting the Tire Pressure Monitoring System.
Sporty driving
The Tire Pressure Monitoring System may be delayed or not be displayed at all when driving with a sporty style, on winter or unpaved roads, or when driving with snow chains.
Calibrating the Tire Pressure Monitoring System
The Tire Pressure Monitoring System must be recalibrated under the following conditions:
The Tire Pressure Monitoring System must only be recalibrated if all tires are inflated to the correct pressure when they are cold. In order to measure the tire pressure on cold tires, the vehicle must be left to stand for 3 hours or only be driven slowly over short distances during this time.
After being warned about a low tire pressure, switch the ignition off and back on. The Tire Pressure Monitoring System can only be recalibrated after this is done.
1. Switch the ignition on.
2. Depending on the vehicle equipment, press the button or function key and open the Vehicle menu in the Infotainment system ⇒ Vehicle settings menu.
Or: depending on the vehicle equipment, press the button or function key.
3. Tap Settings if this key is available.
4. Tap Tires.
5. Tap SET.
6. If all four tires meet the required tire pressure values, tap Confirm.
After travel times of at least 20 minutes and at different vehicle speeds, the system adapts to the new values and monitors them.
WARNING
If the Tire Pressure Monitoring System has been calibrated with a tire pressure that is too high or low, the Tire Pressure Monitoring System may give false warnings or fail to give a warning when the tire pressure is dangerously low.
This can cause accidents and serious or fatal injuries.
Troubleshooting the Tire Pressure Monitoring System

Fig. 190 International tire labeling.
The labeling is on both sides of the tire. In some cases, certain codes may only be on one side of the tire, such as the tire ID number and the production date.
Other digits that may be present are part of the internal labeling from the tire manufacturer or country-specific labeling.
Low-profile tires
Compared to other tire-rim combinations, low-profile tires offer a wider tread surface and a larger rim diameter with shorter tire sidewalls. Low-profile tires improve handling performance and precision. However, they may reduce the level of comfort when driving on roads in poor condition.
Unidirectional tires
The sidewalls on unidirectional tires are marked with arrows. The specified running direction must be followed. This ensures the optimum running characteristics.
If a tire is mounted opposite from the specified running direction, drive more carefully because the tire is not being used the way it was designed to be used. The tire must be replaced or mounted in the correct running direction as soon as possible.
Asymmetrical tires
Asymmetrical tires factor in the behavior of the inner and outer areas of the tread pattern. The sidewalls on asymmetrical tires are marked as the inner and outer side. Maintain the correct position of the tire on the rim.

3) The TIN is the tire serial number.
Uniform Tire Quality Grading (UTQG): Quality grades can be found where applicable on the tire sidewall between the tread shoulder and maximum section width. Example:
For example: Treadwear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Requirements in addition to these grades.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course.
For example, a tire graded 150 (Treadwear-value 150) would wear one-and-one-half (1 1/2) times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.
WARNING
The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A (the highest), B, and C representing the tire's resistance to the generation of heat, and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.
WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.
Tire load and vehicle load, determining the correct load
Vehicles and tires have a limited load capacity. An overloaded vehicle is difficult to steer and brakes less effectively.
Overloading your vehicle can also cause damage to the vehicle and tires, such as tire blowouts and sudden pressure losses.
To ensure your safety and the safety of your passengers, never exceed the maximum vehicle weight. This is specified as the Gross Vehicle Weight Rating (GVWR).
The GVWR includes the weight of your vehicle including all additional equipment, a full fuel tank, all fluids and its maximum load. The maximum load includes the number of people that can travel in the vehicle (number of seats) with an average weight of 150 lbs (68 kg) per person, and also luggage. In trailer mode, the weight of the trailer and the trailer tongue weight rating must be included in calculations.
The Gross Axle Weight Rating (GAWR) is the maximum axle load per axle. The GVWR and GAWR are listed on the safety certificate on the B-pillar on the driver's side.
Your vehicle has either 4 (2 front, 2 rear), 5 (2 front, 3 rear), 6 (2 front, 2 center, 2 rear) or 7 (2 front, 3 center, 2 rear) seats, depending on the type of vehicle. Each seat has a safety belt. As there is an upper limit to the GVWR, the maximum load also has an upper limit. Traveling with a full vehicle or with passengers heavier than 150 lbs (68 kg) per person will reduce the remaining possible load.
The tire inflation pressure label for your vehicle also specifies the maximum weight.
Determining the correct load
The following steps will help you to determine the correct load (total weight of people and other loads in the vehicle).
Steps:
1. Look for the "THE COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX LBS" message on the tire inflation pressure label.
2. Determine the total weight of all people intending to travel in the vehicle (driver and all passengers).
3. Subtract the total weight of all people in the vehicle from the specified weight (XXX KG or XXX LBS).
4. The result of this calculation is the maximum remaining possible load.
For example: If "XXX" = 1400 lbs and five people each weighing 150 lbs are in the vehicle, the remaining possible load is 650 lbs (1400 - 750 (5 x 150) = 650 lbs.).
5. Determine the weight of any luggage you intend to transport in the vehicle. This weight must not exceed the result of the calculation in step 4.
6. If your vehicle is pulling a trailer, the load from your trailer is transferred to your vehicle. Refer to this manual for information about how this reduces the available charge and luggage capacity of your vehicle.
Check the sidewall of the tire to determine the load index specified for the tire.
WARNING
Exceeding the maximum vehicle weight can cause you to lose control of the vehicle and cause accidents resulting in severe and/or fatal injuries.

Uniform Tire Quality Grading (UTQG): A tire information system developed by the U.S. National Highway Traffic Safety Administration (NHTSA) that is designed to help buyers compare tires. UTQG is not a safety rating, nor is it a guarantee that a tire will last for a certain number of miles or perform a certain way. It gives tire buyers more information to compare with factors such as price, brand loyalty and dealer recommendations. Under UTQG, tires are graded by the tire manufacturers in 3 areas: tread wear, traction and temperature resistance. UTQG information is molded into the tire sidewalls.
U.S. DOT Tire Identification Number (TIN): A tire's serial number. It begins with the letters "DOT" ("Department of Transportation") and indicates that the tire meets all federal standards. The next 2 numbers or letters indicate the plant where the tire was manufactured. The last 4 numbers represent the week and year of manufacture. For example, the numbers 1709 mean that the tire was produced in the 17th week of 2009. Any other numbers are marketing codes used by the tire manufacturer.
