Audi Q7: Winter tires

Winter tires significantly improve the vehicle's handling when driving in winter conditions. Because of their construction (width, compound, tread pattern), summer tires provide less traction on ice and snow.

  • Use winter tires on all four wheels.
  • Only use winter tires that are approved for your vehicle.
  • Please note that the maximum permitted speed may be lower with winter tires in General information. An authorized Audi dealer or authorized Audi Service Facility can inform you about the maximum permitted speed for your tires.
  • Check the tire pressure after installing wheels.

The effectiveness of winter tires is reduced greatly when the tread is worn down to a depth of 0.16 in (4 mm). The characteristics of winter tires also decrease greatly as the tire ages, regardless of the remaining tread.

For the sake of the environment

Reinstall summer tires at the appropriate time, because they provide better handling when roads are free of snow and ice. Summer tires cause less road noise, tire wear, and fuel consumption.


You can also use all season tires instead of winter tires. Please note that in some countries where winter tires are required, only winter tires with the  symbol may be permitted.

Snow chains

Snow chains improve both driving and braking in winter road conditions.

  • Only install snow chains on the front wheels.
  • Check and correct the seating of the snow chains after driving a few feet, if necessary. Follow the instructions from the manufacturer.
  • Note the maximum speed of 30 mph (50 km/h). Observe the local regulations.

Use of snow chains is only permitted with certain rim/tire combinations due to technical reasons.

Check with an authorized Audi dealer or authorized Audi Service Facility to see if you may use snow chains.

Use fine-mesh snow chains. They must not add more than 0.53 inch (13.5 mm) in height, including the chain lock.

You must remove the snow chains on roads without snow. Otherwise, you could impair driving ability and damage the tires.


Using incorrect snow chains or installing snow chains incorrectly can result in loss of vehicle control, which increases the risk of an accident.


  • Snow chains can damage the rims and wheel covers* if the chains come into direct contact with them. Remove the wheel covers* first.
  • Use coated snow chains.
  • Do not install and use snow chains if there is a malfunction in the air suspension*, because the vehicle height will be very low. If you drive with snow chains anyway, the wheel housings and other vehicle components can be severely damaged.


When using snow chains, it may be advisable to limit the ESC.

Low-profile tires

Applies to: vehicles with 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.

This results in an agile driving style. However, it may reduce the level of comfort and increase road noise when driving on roads in poor condition.

Low-profile tires can become damaged more quickly than standard tires when driving over large bumps, potholes, manhole covers, and curbs. Therefore, it is particularly important to maintain the correct tire pressure.

To reduce the risk of damage to the tires and rims, drive very carefully on poor roads.

Check your wheels regularly every 2,000 mi (3,000 km) for damage. For example, check for bulges/cracks on the tires or deformations/ cracks on the rims.

After a heavy impact or damage, have the tires and rims inspected or replaced immediately by an authorized Audi dealer or authorized Audi Service Facility.

Low-profile tires can wear out faster than standard tires.

Uniform tire quality grading

  • Tread wear
  • Traction AA A B C
  • Temperature A B C

Quality grades can be found where applicable on the tire side wall between tread shoulder and maximum section width fig. 170.

For example: Tread wear 200, Traction AA, Temperature A.

All passenger car tires must conform to Federal Safety Requirements in addition to these grades.

Tread wear

The tread wear 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 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.


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 .


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.


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.


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.


Temperature grades apply to tires that are properly inflated and not over or underinflated.
