Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rims with a bolted rim 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 £:=?.&..
A 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
314.
- 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

The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
A 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. .,.
