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 Wear Indicator (TWI)
The orig inal tires on your vehicle have
1/16 inch (1.6 mm) hig h "wear indicators"

symbols) indicate the positions of the tread

Tire pressure
Incorrect t ire pressure causes premature wear
and can cause sudden tire blow-out. For this
reason, tire pressure must be checked at least
once a month

Driving style
Driving fast around curves, heavy accelerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear t ires are rotated according to
the tire manufacturer's suggested tire rota-
tion intervals. Please remember the follow-
ing:
- Tire rotation intervals may differ from the
vehicle service intervals outlined 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 manufact urer's suggested
tire rotation intervals.
- Vehicles w ith front -wheel dr ive experience
more tread wear on the fro nt wheels com-
pared to all -wheel drive (quattro) .
- Please rotate tires as shown r:::>

- Extra care must be taken when rotating di-
