Tire service life
The service life of tires depends on a Jot of different things
including proper installation and balancing, correct tire
pressure and driving style .
(r

Tread Wear I nd ica tor ( TWll
Fig. 182 Tire tread:
tr ea d wea r ind ica tors

Fi g. 1 83 Ro tati ng tir es
for mor e even wea r
The or iginal tires on your vehicle have 1/16 inch (1.6 mm) high "wear
indicators":::::, fig. 182 running across the tread . Depending on the
make, there will be six to eight of them evenly placed around the
tire . Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators . Worn tires must
be replaced. Dif ferent figures may apply in other countries:::::,&.
Tir e p re ss ure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out . For this reason, tire pressure must be checked
at least once a month :::::,
page 250.
Drivin g sty le
Driving fast around curves, heavy acce leration 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 tires are rotated according to the
tire manufacturer's suggested tire rotation intervals . Please
r emember the following:
• Tire rotation interva ls may differ from the vehic le service inter
vals 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 manufacturer's suggested tire rotation intervals.
• Vehicles with front -wheel drive experience mo re tread wear on
the front wheels compared to all-wheel drive (quattro®) .
• Please rotate tires as shown :::::, fig . 183.
• Extra care must be taken when rotating direction -specific tires
:::::, page 279.
Whe el b ala n cing
The wheels on new vehicles are balanced. However, various situa
tions during everyday driving can cause them to become unba l
anced, resulting in vibrations you can usual ly feel through the
steering wheel.
Unba lanced whee ls must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must a lso be reba lanced
when a new tire is installed.
