Tir e pres sure
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
c:> page 241.
Driving sty le
Driving fast around curves , heavy acceleration
and hard braking increase tire wear .
Rotating tires for mo re even wear
For all four t ires on your vehicle to have the
same se rvice life, we recommend that the
fro nt and rea r tires are rotated according to
the t ire manufacture r's suggested tire rota­
tion intervals. Please remember the follow ­
ing:
- T ire rotat ion inte rva ls may differ from the
vehicle service intervals outlined in your
Maintenance and Wa rranty 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
fo llow the t ire manufacturer's suggested
t ire rotation intervals .
- Vehicles with front -wheel drive experience
more tread wear on the front wheels com­
pared to all whee l drive (quattro ®).
- Please rotate tires as shown
c:> fig. 194.
-Extra care must be taken when rotating di-
rection-specific tires
c:> page 263 .
Wheel balancing
The wheels on new vehicles are balanced .
H oweve r, va rio us situations d uring eve ryday
driving can cause them to be come unbal­
anced, resu lting in vibrations you can us ually
feel through the steering wheel.
Unba lanced wheels must be rebalanced to
avoid excessive wea r on s teer ing , suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.

Incorrect wheel alignment
Incor rect wheel alignment can cause exces­
sive tire wear, impairing the sa fety of the vehi ­
cle . If tires show excessive wear, have the
whee l alignment checked by an a uthorized
Audi dealer or qualified workshop.
All wheel drive
Vehicles wi th quattro ® must a lways have tires
of the same size, construction and tread type. For details see
<=:> page 191.
_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 ti res are a safety hazard, they do
not grip well on wet roads and increase
your r isk 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 fail sudden ly, especially at high
speeds. T ires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at lower
speeds.
- Never mount used tires on your veh icle if
you are not sure of the ir "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. •
