Traction
The
traction
grades, from highest to lowest,
a re AA, A, B and
C.
Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance¢
.&..
Temperatu re
The
temperature
grades are A (the highest),
B, and C, representing the tire 's resistance to
the generat ion of heat and its ability to dissi-
pate heat when tested under controlled condi-
tions on a specified indoor laboratory test
wheel.
Sustained high temperature
can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature
can lead
to sudden tire fa ilu re ¢ .&..
The grade C corresponds to a level of perform-
ance which all passenger car tires m ust meet
u nder the Federa l Motor Vehicle Safety Stand-
ard No. 109. Grades Band A represent higher
leve ls of pe rformance on the laboratory test
wheel than the m inimum required by law.
_&
WARNING
The traction grade assigned to this tir e is
based on stra ight-ahead braking t raction
tests, and does not include acceleration,
cornering , hydrop laning or peak traction
character istics.
A
WARNING
The temperature
grade for this t ire is es -
tablished for a t ire that is properly inflated
and not overloaded. Excessive speed, un-
derinflation, or excessive loading, either
separate ly or in combination, can cause
heat buildup and possibl e tire fa ilu re.

Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F
(7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require t rue w inter or "snow" t ires, those
with very deeply cut t read. These tires should
o nly be used in pairs and be installed o n all
four wheels . Make sure you purchase snow
ti res that are the same size and cons t ruc t ion
type as the other tires on your vehicle .
Your vehi cle is equipped wit h a ll w heel d rive,
th is w ill imp rove trac t ion d uri ng win t er driv-
ing, even with the standa rd tires. However, we
strong ly recommend that you always equip all
fo ur wheels on your vehicle with correctly fit-
ted winter tires or a ll-season tires, when win -
ter road cond itions are expected. This also im-
proves the veh icle's brak ing performance and
reduces stopping d ista nces .
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur whee ls .
Ask your au t hori zed Aud i d ealer or qualified
workshop for permit t ed
winter tire sizes.
Use
only radial winter ti res .
Win t er ti res lose their effec tiveness whe n the
tread is worn down t o a dep t h of 0 .15 7 inch
(4
mm) .
Only d rive w it h w inte r t ires under w inte r con-
diti ons. Summe r t ires handle bette r whe n
t he re is no snow or ice on the road s an d t he
temperature
is above 45 °F (7 °C).
If you have a flat t ire, see notes on rep lace-
ment whee l ¢
page 233 .
Please a lways remember that winter tires may
have a lowe r s peed rating than the tires orig i-
nally installed on your veh icle at t he time it
was ma nufa ctu red. Please see ¢
page 234,
Speed rating (letter code)
for a list ing of t he
speed ra t ing lette r codes and t he max imum
speed at which the tires can be driven .
