dent.

Low aspect ratio tires
Your Audi is factory-equipped
with low aspect ra-
tio tires . These t ires have been thoroughly tested
and been se lected specifica lly for you r model for
the ir supe rb performance,
road feel and handling
u nder a variety of d riving conditions. Ask your au-
thor ized Audi dealer for mo re de t ails.
The low aspect ratio of these t ires is indicated by
a numera l of 55 or less in the tire's size desig na-
tion . The numera l rep resents t he rat io of the
tire's sidewall he ight in rela ti on t o its tread w idth
expressed in percen t age. Conventional t ires have
a height/w idth ratio of 60 or more .
The performan ce of low-aspect-r atio tire s is par-
ticularly sensitive to impr oper infla ti on pres-
sure. It is therefore important that low aspect
ratio tires are infl ated to the specified pressure
and that the inflation pressure is regularl y
checked and mainta ined. Tire pressures should
be checked at least once a month and alwa ys
before a long trip

What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi-
ly by impact with potholes, curbs, gul lies or
ridges on the road, pa rticularly if the tire is un-
de rinflated .
In order to minimize the occurrence of impact
damage to the t ires of your ve hicle, we recom-
mend that you observe the follow ing precau-
tions:
Wh e el s
- Always maintain recommended
inflat ion pres -
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads wit h potholes, deep
gu llies or ridges . The impact 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, immed iate 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 a ir and
unde rinflat ion, wh ich could eventually cause
t ire fa ilure . If you be lieve th at a t ire may have
been damaged, repla ce the tire as soon as pos-
sible.
- These tires may we a r mo re quickly tha n others.
- Please also remember that, while these t ires
de liver responsive ha nd ling, they may ride less
comfort a bly a nd make more noise t ha n other
choices .
Reduced performance in winter/cold
season
conditions
All t ires are des igned for certai n pu rposes. The
low aspect ratio, ultra high performance t ires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance 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
t ract ion under those conditions . We suggest you
use the recommended
s now or a ll-season tires
spe cified for your veh icle, or the ir equiva lent.
