New tires or wheels
Audi recommends having all work
on tires o r wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowle dge and are eq uipped with
the requ ired too ls and replace­
ment parts.
.,. New tires do not yet have the
optimum g ripping properties .
Drive carefully and at mode rate
speeds for the first 350 miles
(500 km) with new tires.
.,. Only use tires with the same de­
s ign , size (rolling circumfer­
ence), and as close to the same
tread pattern as possible on all
four whee ls .
.,. Applies to: RS models : only use
tires with the same design and
the same tread pattern on all
four whee ls.
.,. Do not replace tires indiv idually .
At least replace both tires on the
same axle at the same time .

Wheels
.,.Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size
¢ 11:,. .
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur­
chase¢ ,&.
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds. For this reason, in case of emer­
gency, only use a spare tire* that
338
is the same circumference as the
regular tires.
~ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than six years old when abso­
lutely necessary and drive
carefully when doing so.
...

Wheels
front and rear axles are the same
size¢&.
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly . To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 368.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
340
.&_ WARNING
-Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can increase the risk of an
accident because it has a neg­
ative effect on handling, driv­
ing through curves, and brak­
ing, and because it increases
the risk of hydroplaning when
driving through deep puddles.
- Applies to: RS models: de­
pending on the equipment,
the widths of the standard
summer tires may be different
on the front and rear axles.
The wider tires are mounted
on the front axle. The tires
must not be rotated .

-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­

A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
@ Note
Snow chains can damage the rims/wheel cov­
ers* if the chains come into direct contact
with them. Remove the wheel covers* first .
Use coated snow chains.
(D Tips
When using snow chains, it may be useful to
switch on sport mode
¢page 149.
Low-profile tires
App lies to: ve hicles with low -profi le tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
la rger r im diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
L ow -profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole
covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire
pressure¢ page 341.
To reduce the risk of damage to the tires and rims, drive very carefully on poor roads.
Check your wheels regularly
every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility .
L ow -profile tires can wear out faster than stand­
ard tires.
Wheels
Uniform tire quality grading
- Tread wear
- Traction AA ABC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width
¢ page 331, fig. 275.
For example: Tread wear 200 , Traction AA, Tem­
perature
A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled cond it ion s on a specified
gov­
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driv ing habits, service practices and
differences in road characteristics and climate.
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 un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
¢,& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire
failure ¢,& .

A WARNING
-The tire pressure monitoring system assists
the driver in monitoring tire pressures . The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This
heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does
not warn about damage or defects in the
tire construction that could cause the tire to burst, for example . Inspect your tires regu­
larly .
(D Tips
-If tires are replaced, the sensors/valves do
not need to be removed or replaced. Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have
questions, see an authorized Audi dealer or
authorized Audi Service Facility .
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit . Have the
sensors replaced by an authorized Audi
dealer or authorized Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
r=;,page 386.
