Tire pressure
Incorrect tire p ressure causes premature wear
and can cause sudden tire blow-out. For this
reason, tire pressure must be checked at least
once a month
c::> page 234.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tir es on your vehicle to have the
same se rv ice life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing:
- T ire rotation inte rva ls may differ from the
vehicle serv ice intervals outlined in your
Warranty
& Maintenance booklet.
- T he longer one tire is used in one location
on the vehicle, the more it wears at certa in
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 whee ls com­
pared to all-whee l drive (quattro).
- Please rotate ti res as shown
c::> fig. 198.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 2 59.
Wheel balancing
The wheels on new vehicles are balanced .
Ho wever, various situations during everyday
driving can cause them to become unbal­
anced, resu lting in vibrations you can usually
feel through the steering wheel.
Unba lanced wheels must be rebalanced to
avoid excessive wea r on steering, suspension
and tires . A wheel must a lso be rebalanced
when a new tire is installed. Incorrect wheel alignment
Incorrect
wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi ­
cle. If tires show excessive wear, have the
wheel alignment checked by an a uthorized
Audi dealer or qualified workshop.
All-wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see
c::>page 195.
_8 WARNING
-Sudden tire fa ilure can lead to loss of con-
trol, 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 t ires are a safety hazard, 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, o il, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fai l suddenly, especially at high
speeds. Tires that are more than 6 yea rs
old can only be used in an emergency
and then w ith specia l care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of their "previous histo­
ry." O ld used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.
