General notes
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle .
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle. Tires are, how­
ever, one of the most important
parts of a vehicle, particularly
considering the comparatively
small patch of rubber on each
tire that assures that all-impor­
tant contact between you, your
vehicle and the road.
Maintaining the correct tire
pressure, making sure that your
vehicle and its tires do not have
to carry more weight than they can safely handle, avoiding
damage from road hazards and
regularly inspecting tires for
damage including cuts, slashes
irregular wear and overall con­
dition are the most important
things that you can do to help avoid sudden tire failure includ­
ing tread separation and blow-
~ outs.

Avoiding damage
If you have to drive over a curb
or similar obstacle , drive very
slowly and as close as possible
at a right angle to the curb.
Always keep chemicals includ­ ing grease, oil, gasoline and
brake fluid off the tires.
Inspect the t ires regularly for
damage (cuts, cracks or blis­
ters, etc.). Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove
them to indicate the direction
of rotation. This ensures you to be able to mount them correct­
ly when you reinstall them.
When removed, the wheels or
tires should be stored in a cool, dry and preferably dark place.
Store tires in a vertical position if they are not mounted on
rims, in a horizontal position if
they are mounted on rims.
New tires
New tires have to be broken in
¢ _&..
The tread depth of new tires
may vary , according to the type .,.

Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, im­
pairing 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 190 .
A 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.
-

-Tires age even if they are not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be
used in an emergency and
then with special care and at lower speeds.
-Never mount used tires on your vehicle if you are not
sure of their "previous histo­ ry ." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
