Tire rotation
Rotating t he tires regular ly is recommended to
ensure the tires wear even ly. To rotate the tires,
install the tires from the rear ax le on the front
axle and v ice versa. This will allow the tires to
have approx imately the same length of service
life.
For unidirectional tires, make sure the tires are
installed according to the running direction indi
cated on the tire
sidewall¢ page 361 .
Hidden damage
Damage to tires and r ims can often occur i n loca
tions that are hidden . Unus ua l vibrations in the

vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas
sengers also depends on making
sure that load limits are not ex
ceeded. Vehicle load includes ev
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi
cle's
Gross Vehicle Weight Rat-
ing
("GVWR"). .,.
339
Wheels
The "GVWR" includes the weight of the basic vehicle, all factory in
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi
mum load includes the number of
passengers that the vehicle is in
tended to carry ("seating capaci ty") with an assumed weight of 150 lbs. (68 kg) for each passen
ger at a designated seating posi
tion and the total weight of any luggage in the vehicle. If you tow
a trailer , the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ
ed as part of the vehicle load.
The Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas
sengers in the vehicle or passen
gers who are heavier than the
standard weights assumed mean
340
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli
ance sticker label located on the
driver's side B-pillar

A WARNING
=
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per
sonal injury, and even death.
-Carry ing more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rim s with a bolted r im ring * or with bolted wheel
covers* consist of multiple pieces. These compo
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble
them ¢_&. .
..&, WARNING
Wheel bolts that are tightened or repaired in
correctly can become loose and result in loss
of vehicle control , which increases the risk of
an accident. For the correct tightening specifi
cation, see
¢ page 35 7, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident .
Winter tires
Winter tires significantly improve the vehicle 's
handling when driving in winter conditions. Be
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac
tion on ice and snow.
.,. Use winter tires on all four wheels .
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
¢ _&. .An
authorized Audi dealer or authorized Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
¢ page 336.
342
The effectiveness of winter tires is reduced great
ly when th e tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re
gardless of the remaining tread.
'
..&, WARNING
- Never drive faster than the maximum per
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice.
{® For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, only
winter tires with the
& symbol may be per
mitted.
Snow chains
-
Snow chains not only improve the driving in win
ter road conditions, but also the braking.
.. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel drive* .
.. Check and correct the seating of the snow
chains after driving a few feet, if necessary . Fol
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.

Use
fine-mesh snow chains . They must not add
more than 0.53 inch (13 .5 mm) in height, includ
ing the chain lock.
You must remove the snow chains on roads with
out snow. Otherw ise, you could impair driving
ability and damage the tires.

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
tio tires. These t ires have been thoroughly tested
and been selected specifically for you r model for
their superb performance, road feel and handling
under a va riety of driving conditions. As k your au
thorized Audi dealer for mo re de tails.
The low aspect ratio of these tires is indicated by
a numera l of
55 or less in the tire's size designa
tion . The numeral represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more .
The performance of low-aspect-ratio tires is par
ticularly sensitive to improper inflation pres
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
Wheels
be checked at least once a month and always
before a long trip
¢ page 336 .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi
ly by impact w ith potholes, curbs, gullies or
ridges on the road, particularly if the tire is un
der inflated.
In order to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom
mend that you observe the following precau
t ions:
-Always maintain recommended inflation pres
sures . Check your tire pressure every
2,000 miles (3,000 km) and add air if necessa
ry.
-Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
-After any impact, immediate ly inspect your
tires or have them inspected by the nearest au
thorized Audi dealer . Replace a damaged tire as
soon as possible .
-Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not a lways
easy to see. Damage can lead to loss of air and
unde rinflation, w hich could even tually cause
t ire fa ilure.
If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos
sible.
-These tires may wear more quickly than others.
-Please also remember that, while these tires
deliver responsive handlin g, they may ride less
comfortably and make more noise than other
choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weather conditions. If you drive under those
c ir cumstances, you should equip your vehicle
..,.

Wheels
with all-season or winter tires, which offer better
traction under those cond itions. We suggest you
use the recommended snow or all-season tires
specified for your vehicle, or their equivalent.
Refer to

tion regarding winter tires.
Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum sect ion w idth
q page 328, fig. 278.
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 conditions on a specified gov
ernment test course .
For examp le, 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 driving 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
q .,&..
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
344
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 ¢.&. .
The grade C corresponds to a level of perform
ance which all passenger car tires must meet un
der the Federal Motor Vehicle Safety Standard
No. 109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
-
The tract ion grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor
nering, hydroplaning or peak traction charac
teristics.
A WARNING
The temperature grade for th is tire is estab
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla
tion, or excessive loading, either separately or
in combination, can cause heat bui ldup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat
ed .
