2013 AUDI A8 winter tires

tread width expressed in percentage. Conven­
tional tires have a height/width ratio of 60 or
more .
The performan ce of low-aspe ct-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 2 55, Checking tire pressure .
What you can do to avoid tire and rim
damage
L ow aspect ratio tir es can be damaged more
eas ily by impact with potho les, curbs, gu llies
or r idges on the road, part icu larly if the tire is
under inflated.
In order to minimize the occurrence of impact
damage to the tir es of your veh icle, we recom­
mend that you observe the following precau­
tions :
- Always maintai n 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 r idges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso
ca use damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
autho rized Audi dealer. Replace a damaged
t ir e as soon as possible.
- Inspect yo ur tires 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
ally cause tire failure . If you be lieve that a
t ir e may have been damaged, replace the
t ir e as soon as poss ible .
- These tires may wear more quick ly than oth ­
ers .
- Please a lso remember that, while these tires
deliver respons ive 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 originally installed on your vehicle are in­
tended 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
shou ld equip your vehicle w ith all-season or
winter tires, which offer better t raction unde r
those conditions. We suggest you use the rec­
ommended snow or all- season tires specified
for your vehicle, or their equivalent.
Refer to~
page 264 for more detailed infor ­
mation regarding winter tires.
Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith t ire pressure monitoring syste m
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended
by the vehicle man ufacturer on the vehicle
placard or tire inflation pressure labe l. (If your
vehicle has tires of a different size than the
s iz e in dicated on the vehicle placard or tire in­
flat ion pressure label, you should determine
the proper tir e inflation pressure for those
tires) .
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one o r more of your
tires is s ignificantly under-inflated. According­
l y, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possible, and inflate them to the
proper pressure . Driving on a significantly un ­
der-inflated tire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al-
so reduces fuel effic iency and tire tread life, ..,.
