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

Tread W ear Indicator (TWI)
The origina l tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 210 runn ing across the tread. Depend ­
ing on the make, there will be six to eight of
them evenly placed around the t ire. Marks on
the t ire s idewall (for example " TWI" or other
Tires and wheels 255
symbols) indicate the positions of the t read
wear indicato rs . Worn tires must be replaced .
D ifferent f igures may apply in other countr ies
<=> ,&. .
Tire pressure
Incor rect t ire pressure ca uses p remature wea r
and can cause sudden tire blow -out . For this
reason, tire pressure must be checked at least
once a month
c:> page 251.
Driving style
Drivi ng fast around curves, heavy acce lerat ion
and hard brak ing increase tire wear .
Rotating tires for more even w ear
Fo r all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires a re rotated ac cord ing to
the tire man ufact urer's suggested tire ro ta­
tion intervals . Please remembe r the follow­
ing:
- Tire rotation in tervals may differ from the
veh icle servi ce interv als outlined in your
Warra nty & Maintena nce booklet.
- The longe r one tire is used in one lo cation
on the vehi cle, the more it wears at certain
points ; there fore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals.
- Ve hi cles with front-wheel drive exper ience
more tread wear on the front w heels com­
pared to a ll-wheel dr ive (quattro) .
- Please rotate tires as shown
c::> fig . 211.
- Extra care must be taken when rotating di-
rection-specific tires
c::> page 2 75.
Wheel balancing
The wheels on new ve hicles are balanced.
However, various s ituations dur ing everyday
driv ing ca n cause them to become unba l­
anced, resulting in vib rat ions you can usually
feel t hrough the steer ing whee l.
U nbalanced wheels must be rebalanced to
avo id excessive wear on steering, s uspension
and tires . A whee l must also be reba lanced
when a new tire is insta lled .
