Tires and wheels
Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particular ly considering the comparative ly sma ll patch
of rubber on each tire that assures that all -important 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 regular ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overal l condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avo iding d am age
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.
A lways keep chemica ls including grease, oil, gasoline and brake
flu id off the ti res .
I nspect the tires regularly for damage (cuts, cracks or blisters, etc .!.
Remove any foreign bodies embedded in the treads .
Storing tire s
Mark tires when you remove them to indicate the direction of rota ­
tion. This ensures you to be ab le to mount them correctly when you
reinstall them. When removed, the whee
ls or tires should be stored in a coo l, dry
and preferably dark place.
Store tires in a vertical position i f they are not mounted on r ims, in
a horizontal position if they are mounted on rims.
N ew tire s
New tires have to be broken in => &.
The tread depth of new tires may vary, according to the type and
make of tire and the tread pattern.
Hidd en d am ag e
Damage to tires and rims is often not readily visible . If you notice
unusua l vibration or the vehic le pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an author ized Audi dealer or qualified workshop .
Uni dir ection al tire s
A unidirect ional tire can be identified by arrows on the sidewa ll, that
point in the direction the tire is designed to rotate. You must fo llow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
=> page 298.
Rim s with bolted rim ring *
Light-alloy wheels with a bo lted rim ring consist of several parts .
These parts are screwed together with special bo lts, using a specific
technique. This ensures proper function, seal, safety, and true running of the wheel. For this reason, damaged rims shou ld be
replaced, and you should never repair or dismantle them
=> & .
Rim s with screw -on decorative co vers *
Light-a lloy whee ls can be furnished with interchangeab le decora -
tive covers that are mounted to the rim with se lf -locking bolts. ...
