Winter tires
Winter t ires 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 inst alled on all
four wheels. Make sure you purchase 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. However, we
strongly recommend that you always equip all
four wheels on you r vehicle with correctly fit-
ted winter tires or all -season tires, when w in-
t er road 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 Audi dealer or qualified
workshop for permitted winter tir e sizes. Use
only radia l winter tires.
W inte r t ires 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-
ditions . Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is
above
45 °F (7 °C).
If you have a flat tire, see notes on spare
wheel

page 246.
Please always remember that w inter t ires may
have a lower speed rating than the t ires origi-
nally installed on your vehicle at the t ime it
was manufactured. Please see

page 247 ,
Speed rating (letter code) for a Listing of the
speed rating letter codes and the maxim um
speed at which the tires can be driven .
The speed rating letter code

Winter t ires have maximum speed lim its
that may be lower than your vehicle's max-
imum speed. Always know the maximum
speed before dr iving 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 serious
personal injury to you and your passen-
gers .
A
WARNING
,..___
-
Driving faster than t he maximum speed
for which the winter tires on your vehicle
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

Always adju st your dr iving to the road and
traffic condit ions . Never let the good ac-
celeration of the winter t ires and al l wheel
drive tempt you into ta king ext ra risks. Al-
ways remember:
- When braking, an all wheel drive vehicle
handles in t he same way as a front drive
vehicle .
- Drive carefully and 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 . They are qu ieter, do not wear
as quickly and reduce fuel consumption .
