then only for a short period of time. In this case,
please drive with extra care. Refit a normal road
wheel as soon as possible.
Applies to vehicles with four-wheel drive:
wheels must always be fitted with tyres of the
same type, make and tread pattern, as the drive­
line could otherwise be damaged by variations in
the wheel speeds. For the same reason, only use
a spare wheel* which has the same rolling cir­
cumference as the normal road wheels.
Manufacturing date
The manufacturing date is indicated on the tyre
sidewa ll (possibly on Ly on the inner side of the
wheel):

WARNING
-Use only tyre/rim combinations and match­
ing wheel bolts approved by Audi. Otherwise
damage to the vehicle and an accident could
result.
-For technical reasons, it is not possible to
use wheels from other vehicles. In certain
cases, it is not even possible to use wheels
from another vehicle of the same model.
-It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not
rely entirely on the nominal tyre size marked
on the tyre; with some makes of tyre the ef­
fective tyre size can differ significantly from
the nominal dimensions, even though the
tyres have the same size designation. Inade­
quate tyre clearance can result in damage to

Tyre wear/ damage

Tyre wear
Inspect the tyres regularly for damage.
-The wear on under or over-inflated tyres is sig­
nificantly higher.
- Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
-If you notice excessive tyre wear, have the
wheel alignment checked by a qualified work­
shop.
- Have your tyres rebalanced if steering wheel vi­
brations indicate an imbalance. Otherwise, the
tyres and other parts of the vehicle may wear
faster.
Tread wear indicators
The original tyres on your vehicle have 1.6 mm
high tread wear indicators c::::>
across the tread at regular intervals. The letters
"TWI" or triangles on the sidewall indicate the
positions of the tread wear indicators.
