Wheels
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rim s with a bolted r im ring * or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble
them ¢_&. .
..&, WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control , which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢ page 35 7, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident .
Winter tires
Winter tires significantly improve the vehicle 's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion 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
¢ _&. .An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
¢ page 336.

The effectiveness of winter tires is reduced great­
ly when th e tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re ­
gardless of the remaining tread.
'
..&, WARNING
- Never drive faster than the maximum per ­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice.
{® 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.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
-
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
.. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel drive* .
.. Check and correct the seating of the snow
chains after driving a few feet, if necessary . Fol­
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
.,.

Wheels
with all-season or winter tires, which offer better
traction under those cond itions. We suggest you
use the recommended snow or all-season tires
specified for your vehicle, or their equivalent.
Refer to
q page 342 for more detailed informa­
tion regarding winter tires.
Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum sect ion w idth
q page 328, fig. 278.
For example: Tread wear 200 , Traction AA, Tem­
perature
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 gov­
ernment test course .
For examp le, a tire graded 150 would wear one
and one half
(1 1/2) times as well on the govern­
ment 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, Band
C. Those grades represent the tire 's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
q .,&..
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
344
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 mate­
rial 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 perform­
ance which all passenger car tires must meet un­
der 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.
A WARNING
-
The tract ion grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for th is tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat bui ldup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed .
Tire pressure monitoring
system
(1) General notes
App lies to : vehicles with tire pressure mo nitori ng syste m
.
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your veh icle has
tires of a different size than the size ind icated on
the veh icle placard or tire inflat ion pressure
