250 Tire s and wheel s
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 " tires, those
with very deeply cut tread. These t ires shou ld
only be used in pairs and be ins talled on all
four wheels. Make sure you pu rchase snow
tires that are the same size and const ruction
type as the other tires on your vehicle.
Your veh icle is equipped with all whee l drive ,
this wi ll improve tract ion du ring w inter driv­
ing,
even with the standard tires. Howeve r, we
strongly recommend that you a lways equip a ll
four wheels on you r vehicle with correctly fit­
ted winter tires or all -se ason tires, when w in ­
t e r r oad conditions are expected . This also im­
proves the vehicle's braking performance and
reduces stopping distances .
Summe r tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your autho rized Aud i dea ler or qualified
workshop for permitted
wi nter tir e sizes . Use
only radia l winter tires.
W inte r tir es lose the ir effe ctiveness when the
tread is worn down to a depth of
0.15 7 inch
(4 mm).
Only drive with winter tires unde r winter con­
d itions . Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is
above 45 °F ( 7 °C).
I f you have a flat tire, see notes on spare
wheel
9 page 246.
P lease always remember that w inter t ires may
have a lower speed rating than the t ires origi­
na lly installed on your vehicle at the t ime it
was manufactured. Please see
9 page 247 ,
Speed rating (letter code)
for a List ing of the
speed rating letter codes and the maxim um
speed at which the tires can be driven . The speed rating letter code
(
¢ page 23 7) is
on the side wall of the tire
9 page 246 .
A WARNING ,-
Winter tires have maximum speed lim its
that may be lower than your vehicle's max­
i mum speed. Always know the max imum
speed before dr iv ing off . Never dr ive faster
than the speed permitted for yo ur specific
winter tires. This wi ll cause damage to the
tires leading to an accident and ser ious
personal injury to you and your passen­
gers .
A WARNING ,..___ -
Driving faster than the maximum speed
for which the winter tires on your ve hicle
were designed can cause tire fail ure in­
cluding a blowout and sudden deflation, loss of control, crashes and ser ious per­
sonal injuries. Have worn or damaged tires
replaced immediately .
- W inter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on yo ur vehicle are rated .
A WARNING
-Always ad just your dr iv ing to the road and
traffic condit ions . Never let the good ac­
celeration of the winter t ires and al l wheel
drive tempt yo u into ta king ext ra risks. Al­
ways remember:
- When braking, an all wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive c arefully a nd reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
@ For the sake of the environment
Use summer tires whe n weather condi­
tions permi t. T hey are qu ieter, do not wear
as quickly and reduce fuel consumption .

28 2 Con sum er Inf ormation
