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
<=:> page 237.
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
<=:> fig. 192.
-Extra care must be taken when rotating di-
rection-specific tires
c:> page 259 .
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 whee ls 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.
Tire s an d wheel s 241
Incorrect wh eel 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 authorized
Audi dealer or qualified workshop.
All wheel drive
Vehicles wi th quattro must always have tires
of the same size, construction and tread type.
For details see
<=:> page 192.
_8 WARNING
Sudden tire fa ilure can lead to loss o f con­
trol, a crash and serio us personal in jury!
- 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 thei r "previo us histo­
ry ." O ld used tires may have been dam­
aged even thoug h the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control. •

tions when d ispos ing of old engine oil,
