Traction
The traction grades, from highest to lowest,
are AA, A, Band
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
c:> .&..
Temperatu re
The temperature grades are A (the highest),
B, and
C, representing the t ire's resistance to
the generat ion of heat and its ability to dissi-
pate heat when tested under con t rolled cond i-
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 failure
c:> ,& .
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet
under 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 t ire is
based on stra ight-ahead braking traction
tests, and does not include acceleration,
cornering, hydrop laning o r 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 ove rloaded. Excessive speed, un-
derinflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible ti re fa ilure.

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 true winter or "snow" t ires, those
with very deeply cut tread . These tires should
only be used in pairs and be installed on a ll
four wheels . Make sure you purch ase snow
t ires that are the same size and cons t ruction
type as the othe r tires on your vehicle.
If your vehicle is equ ipped w ith all-whee l
drive, t his will improve tra ction during winte r
driving, even with the standard tires . Howev-
er, we strongly recommend that you always
equip all four wheels on your vehicle w ith cor-
rect ly fitted winter tires or all-season t ires,
when winter road condit ions are expected.
This also improves the veh icle's brak ing per-
formance and reduces stopping d istances .
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all fo ur whee ls .
Ask your au t hori zed Audi dealer or qualified
workshop for permit t ed
winter tire sizes. Use
only radial winter tires .
Winter tires lose their effec tivenes s whe n the
tread is wo rn down t o a depth of 0 .157 inch
(4 mm) .
Only d rive with winter t ires under w inte r con-
dit ions. Summe r t ires handle bet te r whe n
the re is no snow or ice on the roa d s an d t he
temperatu re is above 4 5 °F (7 °C).
If you have a flat ti re, see notes on spare
whee l

Please a lways remember that winter tires may
have a lowe r speed rating than the tires origi-
nally installed on your vehi cle at the time it
was ma nuf actu red. Please see
