Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv
ing style.

The origina l tires on your veh icle have
1/16 in ch (1.6 mm) high "wear ind icators"
r::!;> fig . 178 run ning across the tread. Depend
ing on the make, there will be six to eight of
them evenly p laced around the t ire . Marks on

symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced.

Tir e pressure
Incorrect tire pressure causes premat ure wear
and can cause sudden tire blow-out . For th is
reason, tire pressure must be checked at least
once a month
r::!;> page 23 7.
Dri ving sty le
Driving fast around curves , heavy acceleration
and hard braking increase tire wear. Tires and wheels 241
Rotating tires for more even wear
For all four tires on your ve
hicl e to have the
same service life, we recomme nd that the
front and rear tires are rotated according to
the tire manufacturer 's suggested tire rota
tion inte rvals. Please remember the follow
ing :
- Tire rotation intervals may differ from the
veh icle service inte rva ls o utlined in your
Warranty & Maintenance booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend that you
follow the tire manufactu rer 's suggested
tire rotation intervals .
- Vehicles w ith front-wheel dr ive exper ience
more tread wear on the front wheels com
pared to all -wheel d rive (quattro ®).
- Please rotate tires as shown
r::!;> fig. 179.
-Extra care must be taken when rotat ing di-
rection-specific tires
r::!;> page 258 .
Wheel balancing
The wheels on new veh icles are balanced .
However, various situations during everyday
driving can cause them to become unba l
anced, resulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, s uspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Inco rrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impair ing the safety of the vehi
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualified workshop.
All-whe el drive
Vehicles wi th quattro ® mus t always have tires
of the same size, construction and tread type. For details see
