2009 AUDI S6 service

-Tires and wheels
PW-------------------
& WARNING (continued)
• Run flat tires may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassis designed
for run flat tires. Incorrect use of run flat tires can lead to vehicle
damage or accidents. Check with an authorized Audi dealer or tire
specialist to see if your vehicle can be equipped with run flat tires.
If run flat tires are used, they must be installed on all four wheels.
Mixing tire types is not permitted.
0 Note
• For technical reasons , it is not generally possible to use the
wheel rims from other vehicles. This can hold true for wheels of the
same vehicle type .
• If the spare tire is different from the tires that you have mounted
on your vehicle (for example winter tires or wide profile tires), then
use the spare tire for a short period of time only and drive with extra
care. Replace the flat tire with the tire matching the others on your
vehicle as soon as possible.
• Never drive without the valve stem cap. The valves could get
damaged.
~ For the sake of the environment
Dispose of old tires in accordance with the local requirements. •
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~
page 329,
fig. 251 .
For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require ­
ments 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 ti re graded 150 wou Id 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 condi­
tions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differ­
ences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band 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
~ & .
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 dissi­ pate 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 Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law. .,_

wheel bolts ~ page 346.
4. Locate the proper mounting point for the jack and align
the jack below that point~
page 347.
5. Lift the car with the jack~ page 347.
6. Remove the wheel with the flat tire and then install the
spare
~ page 348.
7. Tighten all wheel bolts lightly.

After changing a vvheel
A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
-Check the tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
replaced as soon as possible.
[ i] Tips
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Drive at reduced speed until you have the tightening torques
