Wheels
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than 6 years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1.6 mm) high
"wear indicators" ¢fig.
