wheel alignment AUDI S3 2015 Owners Manual

-The longer one tire is used in one location on the vehicle,
the more it wears at certain points; therefore, we recom­
mend that you follow the tire
manufacturer's suggested tire
rotation intervals.
-Vehicles with front-wheel drive experience more tread
wear on the front wheels com­ pared to all-wheel drive (quat­
tro).
-Please rotate tires as shown
¢ fig. 171.
-Extra care must be taken when
rotating direction-specific
tires

Wheel balancing
The wheels on new vehicles are balanced. However, various sit­
uations during everyday driving
can cause them to become un­
balanced, resulting in vibra­
tions you can usually feel
through the steering wheel.
Unbalanced wheels must be re­
balanced to avoid excessive
wear on steering, suspension
and tires. A wheel must also be
rebalanced when a new tire is

Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, im­pairing the safety of the vehi­
cle. If tires show excessive
wear, have the wheel alignment checked by an authorized Audi
dealer or qualified workshop.
All-wheel drive
Vehicles with quattro must al­
ways have tires of the same size, construction and tread
type. For details see
¢ page 193 .
.8, WARNING
Sudden tire failure can lead
to loss of control, a crash and serious personal injury!
-Never drive a vehicle when the tread on any tire is worn down to the wear indica­
tors.
-Worn tires are a safety haz­ ard, they do not grip well on
wet roads and increase your risk of "hydroplaning" and
loss of control.
-Always keep chemicals that can cause tire damage, such
-
as grease, oil, gasoline and
brake fluid away from tires.
