What you c an do to avoid tire and rim
damage
Low aspect rat io tires can be damaged mor e easi·
ly by i mpact with pot h oles, cur bs, gu lli es or
ri
dges on the road, particular ly if th e tire is u n·
der in fl ate d.
In order to minimize the occurrence of impact
damage to the ti res of your ve hi cle, we recom·
mend that you observe the following precau·
t ions:
- Always
maintain recommended inflation pr es·
sures . 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 ri dges . The impact from driving
through or over such obstacles can damage
your t i res . Impact with a curb may also cause
damage to your tires.
- Aft
er any impact, immediately inspect your
t ir es or have them inspected by the ne ar e st au-
th orized Aud i dea ler. Replace a dam age d tire as
so on as p oss ible.
- Inspe
ct your t ir es every 2,0 00 mil es (3, 00 0 km)
for d
am age and wear. Damage is not always
easy to
see. Damage can l ead to l oss of air an d
un
der inflation, which could eventually cause
tire failure. If you believe that a t ire may have
been damaged, rep l ace the tire as soon as pos-
sible.
- These
tires may wea r more quickly than others.
- Please also remember that , while these tires
deliver responsive handling , they may ri de less
comfortably and make more noi se than other
choices.

Reduced performance in winter / cold season
conditions
All tir es are designed for ce r tain purposes . The
low
aspect rat io, ult ra high performance tires
originally 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 wi nter tires, which offer better
tra ct ion un der those conditions. We suggest you
use the rec omme n ded snow or all -season t ires
sp ecified for your vehicle, or their equival ent.

- T emperatu re ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulde r and
maximum section width Q page 250 , fig. 192.
For ex amp l e: Tread wear 20 0, Traction AA , Tem-
perature A.
All
passenger car tires must conform to Federal
Saf
ety Requirements in addition to these grades.
Tread wear
Th e tread wear gr ade is a compa rative rating
b
as ed on th e w ear r ate of t he tire wh en teste d
under c
ontr olled co nditions on a specif i ed gov·
ernm en t t es t course.
For ex
amp le, a tire gr aded 150 would wear one
and one half (1 1 /2) times as well on the govern-
ment course as a tire graded 100.
T he re la tive per f ormance of tires depends u pon
t he act ual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service pract i ces and
differences in road characterist ics and cli mate.

The traction grades , from highest to lowest, are
A A, A, Band C. Those grades represent the tire's ~
