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 tires 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 .,.

In certain circumstances, you may not use
wheel bo lts from a different vehicle -
even if it

Q page 291.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
control, a collision and ser ious personal in­
jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose w hile d riving if greased or
o iled,
even if tightened to the spec ified
torq ue.
- Only use wheel bo lts that belong to the
rim being ins talled.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the correct tightening
torque fo r the wheel bolts to reduce the
risk of a wheel loss. If the tigh teni ng tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving . If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel ca n be­
come loose .
(D Note
The specified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of
± 7,4 ft lb(± 10 Nm). Torque whee l bolts
diagonally. After changing a wheel, the
torque must be checked as soon as possi­
b le with a torque wrench -prefe rably by an
author ized Audi dealer or qualified wo rk­
shop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires . These tires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
Tire s an d wheel s 263
and handling under a variety o f driving condi ­
tions. Ask your authorized A udi dealer for
more details .
T he low aspec t ratio of these tires is ind icate d
by a numera l of
55 or le ss in the tire's size
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage.
Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-a spect-ratio tire s is
particularl y sens it iv e to improper inflation
pressure. It is therefore important that low
a spect ratio tir es are inflated to the specified
pre ssure and that the inflation pr essure i s
regularly checked and ma intain ed . Tire pr es­
s ure s should be checked at lea st on ce a
month and alway s bef ore a long trip
~ page 245 , Checking tire pressure .
A Word about Low Aspect Ratio and High
Performance Ti res
Hig h pe rformance tires are des igned for bet­
ter performance and handling in warm cli­
mates. When driving in cold, snowy or icy
weather, you sho uld equ ip your vehicle w it h
four all-season or winter tires, which
offer
better traction under those condit ions. We
suggest you use the Audi recommended win­
te r or a ll-season tires specified for you r Audi.
High performance tires a lso have a lower as ­
pect ratio that aids performance and han­
dling . Driving over rough or damaged road
surfaces, as well as debr is, cu rbs and other
obstacles can cause serious damage to
whee ls, tires, vehicle body, and suspens ion
parts . B e carefu l to avo id road hazards and re­
du ce your speed , espec ia lly if your vehicle is
equipped wi th low prof ile tires .
Please a lso remember when making your se­
lection that, wh ile these tires deliver respon­
s ive handling, t hey m ay ride less comfo rtably
and make more noise than o thers . Finally,
these tires may wear more quickly than other
c h oices.
