The tires and rims are essential
parts of the vehicle's design.
The tires and rims approved by
Audi are specially matched to
the characteristics of the vehi­
cle and can make a major con­
tribution to good road holding and safe handling when in good
condition and properly inflated
¢ A .
We recommend that all work
on tires and wheels be per­
formed by an authorized Audi
dealer. They are familiar with recommended procedures and
have the necessary special tools
and spare parts as well as the
proper facilities for disposing of
the old tires.
Authorized Audi dealers have
the necessary information

and handling under a variety of driving condi­
tions. Ask your authorized Audi dea ler for
more deta ils.
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's size
designation. The numeral represents the ratio
of the tire's sidewa ll height in relation to its
trea d width expressed in percentage. Conven­
ti onal tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure . It is therefore important that low
aspect ratio tires are inflated to the specified
pressur e and that the inflation pressure is
regularly checked and maintained. Tire pres­
sures should be checked at least once a
month and always before a long trip
¢ page 221, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potho les, curbs, gullies
or ridges on the road, particu larly if the tire is
underinflated .
I n order to minimize the occ urrence of impact
damage to the tir es of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary .
- Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
t hr ough or over such obstacles can damage
your tires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
t ir es or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ir e as soo n as possible.
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear. Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu-
Tires and wheels 239
ally cause tire failure. If you believe that a
tire may have been damaged, rep lace the
tire as soon as possib le.
- These tires may wear more quickly than oth­
ers.
- Please also remembe r that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires or iginally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy o r icy weather conditions. If
you drive under those circumstances, you
should equip your vehi cle w ith all-season or
winter tires, which offer better traction under
those conditions. We suggest you use the rec ­
ommended snow or a ll-season tires specified
for your vehicle, or their equivalent.
Refer to¢
page 236 for more de tailed infor­
mation regarding winter tires.
Ti re pressure
monitoring system
ill General notes
Applies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
sho uld be checked monthly when cold and in ­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s ize indicated on the vehicle placard or tire in­
flat io n pressure label, you should determine
the proper t ire inflation pressu re for those
tires).
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system (TPMS) that illum inates a low tire
pressure te llt ale when one or more of your
tires is significantly under-inflated. .,.
