Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Aud i dealer for
more details .
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 sidewall height in relation to its tread width expressed in
percentage. Convent ional 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 pressure 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
252, "Checking t ire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact w ith
potholes, curbs, gullies or ridges on the road, particularly if the tire is
unde rinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle , we recomme nd 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 necessary.
• Drive carefully on roads with potholes, deep gullies or ridges. The
impact from driving through 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 tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflat ion, which could eventually cause tire fa ilure . If
you believe that a tire may have been damaged, replace the tire as
soon as poss ible .
• These ti res may wear more quickly than ot hers.
• Please a lso remember that, while these tires deliver responsive
hand ling, they may ride less comfortably and make more no ise than
other choices .
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra
high performance t ires originally installed on your vehicle are
intended for maximum dry and wet road pe rfo rmance and handling .
They are not su itable for cold, snowy or icy weather conditions . If you
drive under those circumstances, you should equip your vehicle with
all-season or w inter tires, which offer better traction under those
conditions . We suggest you use the recommended snow or all-season
tires specified for your veh icle, or their equivalent .
Refer to => page 261 for more detailed information regard ing winter
tires. •

General notes
1
Each tire, including the spare (if prov ided) , shou ld be checked
month ly when cold and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the vehicle placard or t ire
inf lation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper t ire inflation pressure for
those tires.)
