The correct tire pressure for the
spare wheel is located on a la­
bel on the driver's side B-pillar.
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label on your vehicle with the tires on
your vehicle. Make sure that the tire size information on the ve­
hicle label is the same as the
size of the tires on the vehicle.
This is especially important if
the vehicle belongs to someone
else or you bought the vehicle
with different rims/tires or you
bought the vehicle as a previ­
ously owned vehicle. Remember, your safety and
that of your passengers also de­ pends on making sure that load
limits are not exceeded. Vehicle
load includes everybody and ev­
erything in and on the vehicle.
These load limits are technical- ly referred to as the vehicle's
Gross Vehicle Weight Rating ("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the maximum load that can be ap­
plied at each of the vehicle's
two axles. The Gross Vehicle
Weight Rating and the Gross
Axle Weight Rating are listed on the safety compliance stick-
er label located on the driver's
side B-pillar. The tire pressure label on your Audi lists the

We recommend that all work
on tires and wheels be per­
formed by an authorized Audi
dealer. They are familiar with
recommended p rocedures and
have the necessary special too ls
and spare parts as well as the proper facilities for disposing of
the old ti res.
Autho rized Audi dealers have
the necessary information
about technical requirements
for installing or changing tires

Replacing tires and wheels
Tires sho uld be replaced at
least in pairs and not individu­

Always buy replacement radial

are u sed , they must be in­

mitted.
(D Note
-For technical reasons, it is not generally possible to
use the wheel rims from
other vehicles. This can hold
true for wheels of the same
vehicle type.
- If the spare tire is different
from the tires that you have mounted on your vehicle
(for example winter tires or
wide profile tires), then use
the spare tire for a short pe­ riod of time only and drive
with extra care. Replace the
flat t ire with the tire match­

cle as soon as possible.
- Never drive without the
valve stem cap. The valves
could get damaged .

Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure<=>,& .
The grade C corresponds to a level of perform­
ance which a ll passenger car tires must meet
under the Federa l Motor Veh icle Safety Stand ­
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.
A WARNING
The traction grade assigned to this t ire is
based on stra ight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplanin g or peak traction
characteristics.
A WARNING ,.,.____
The temperature grade for this tire is es­
tablished for a tire that is properly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
separately or in combination, can cause heat buildup and possible tire 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, loca l governments
may require true winter or "snow" tires, those
with very deeply cut tread. These t ires should
only be used in pairs and be installed on all
four wheels. Make sure you purchase snow
tires that are the same size and construct ion
type as the other tires on your ve hicle.
Your veh icle is equipped with all -wheel drive,
this will improve traction during w inter driv­
i ng, even with the standard tires. However, we
strongly recommend that you always equip all
four whee ls on your veh icle w ith correctly fit­
ted winter ti res or all-season tires, when win­
ter road conditions are expected. This a lso im- proves the vehicle's
braking performance and
reduces stopping distances.
Summer tires provide less gr ip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your authorized Audi dealer or qualified
workshop for perm itted
winter tire sizes . Use
only rad ial winter t ires .
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0.157 inch
(4 mm).
Only drive w ith w inter t ires under winter con ­
ditions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
wheel<=>
page 291 .
Please always remember that winter tires may
have a lower speed rating than the tires origi­
nally installed on your vehicle at the time it
was manufactured. Please see
<=>page 294,
Speed rating (letter code)
for a listing of the
speed rating letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code (<=>
page 2 76) is
on the side wall of the t ire
c> page 291.
A WARNING ,.___
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed before driv in g off. Never drive faster
than the speed permitted for your 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 the maximum speed
for which the winter tires on your vehicle were designed can cause t ire failure in­
cluding a blowout and sudden deflation,
