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.

Tread Wear Indicator (TWI)
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
the t ire s idewall (for example "TWI" or other
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
Ma intenance and Warranty 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 w heel drive (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 wheel drive
Vehicles wi th quattro ® must a lways have tires
of the same size, construction and tread type. For details see
r=> page 190 .
