Tires and wheels -_______________ _____.
Tire service life
The service life of tires depends on a lot of different things
including proper installation and balancing, correct tire
pressure and driving style.

Tread Wear Indicator (TWI)
Fig . 175 Tire tread:
tread wear indicators
(TWI)
Fig . 176 Rotating tires
for more even wear
The original tires on your vehicle have 1/16 inch (1.6 mm) high "wear
indicators":::::, fig. 175 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. Different figures may apply in other countries.:::::,&.
Tire pressure
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 249.
Driving style
Driving fast around curves, heavy acceleration 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
remember the following:
• Tire rotation intervals may differ from the vehicle 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 more tread wear on
the front wheels compared to all-wheel drive (quattro®l .
• Please rotate tires as shown .:::::, fig. 176.
• Extra care must be taken when rotating direction -specific tires
:::::, page 277.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel.
Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed. _,,
