Low aspect ratio tires
Your Audi is factory-equipped
with low aspect ra-
t io ti res. These t ires have been tho rough ly tested
a nd been se lected specifically fo r your model for
t he ir superb performance,
road feel and handling
under a variety of driving conditions. Ask your au-
thor ized Audi dealer for more details .
The low aspect ratio of these t ires is indicated by
a numera l of 55 or less in the tire 's size designa -
tion. The numera l represents the rat io of the
tire's sidewall height in relat ion to its tread width
expressed in pe rcentage. Conventional t ires have
a height/w idth rat io of 60 or more.
The performan ce of low- aspect-ratio tire s is par-
ticularl y sensitive to imp roper inflat ion pres-
sure. It is therefore import ant that low aspect
ratio tires are infl ated to the specified pressure
and t hat the inflation pressure is regularl y
checked and mainta ined. Tire pressures should
be checked at least once a month and alwa ys
befor e a long t rip

What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi-
ly by impact with potho les, curbs, gull ies or
Wh e el s
ridges on the road, particular ly if the tire is un -
deri nflated.
In orde r to min imize the occurrence of imp act
damage to the tires of your vehicle, we recom-
mend that you observe the following preca u-
tions:
- Always ma intain recommended
inflat io n pres-
sures. Check your ti re pressure every 2,000
miles (3,000 km) and add air if necessary .
- Drive ca refully on roads with pot holes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have them inspected by the nearest au -
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see . Damage can lead to loss of air and
underinflation,
wh ich could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged, replace the tire as soon as pos-
sib le.
- These tires may wear more quickly than others .
- Please also remember that, while these tires
delive r responsive ha ndling, they may ride less
comfortably a nd make more noise than other
choi ces.
Reduced perfo rmance in winter /c old season
conditions
All tires are des igned for certai n purposes. The
low aspect ratio, ultra high performance t ires
origina lly installed o n your veh icle are intended
for maximum dry and wet road per formance and
handling . They are not suitable for cold, snowy or
icy weather conditions . If you drive under those
circumstances, you should equip your vehicle
with all-season or winter tires, which offer better
tract ion under those conditions. We suggest you
use the recommended
snow or all-season tires
spec ified for your veh icle, or their equiva lent .
Refer to ¢ page 222 for more detailed informa-
t ion regarding winter tires.
