The tires and rims are essential parts of the vehicle's design . The tires
and rims approved by Audi are specially matched to the characteris­
tics of the vehicle and can make a major contribution to good road holding and safe handling when in good condition and properly
inflated
~ & .
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer . They are familiar with recommended proce­
dures and have the necessary special tools and spare parts as well as
the proper facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech­
nical requirements for installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together) .
Be sure to read and heed the information to the tire pressure moni­
toring system* ~
page 314.
Always buy replacement radial tires that have the same specifications
as the tires approved for your vehicle by Audi. Replacement tires must
always have the same load rating specification as the original equip ­
ment or approved optional tires listed in the table~
page 299.
Audi-approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle
. The table
(~ page 299) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located on driver's side B-pillar (~
page 299,
fig. 217) lists the specifications of the original equipment tires
installed on your vehicle at the time it was manufactured.
Federal law requires tire manufacturers to place standardized infor­
mation on the sidewall of all tires~
page 307, fig. 220 . This infor­
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a tire identification number
for safety standard certification and in case of a recall.
Tire specifications
Knowledge of tire specifications makes it easier to choose the correct
tires . Radial tires have the tire specifications marked on the sidewall,
for example:
P245 / 45 R 17 99 H XL
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
245 Nominal tire width in mm of the tire from sidewall edge to side-
wall edge. In general, the larger the number, the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction : Radial
17 Rim diameter code (in inches)
99 Load rating code
H Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF") indicates that the tire is a"Rein­
forced" or an "Extra Load" tire
M+S (or "M/S") Indicates that the tire has some mud and snow capa­
bility
The tires could also have the information of direction of rotation
~page 295.

Tire manufacturing date
The manufacturing date is also indicated on the tire sidewall
(possibly on ly on the
inner s ide of the wheel):
"DOT ... 2210 ... " means, for example, that the tire was produced in
the 22nd week of 2010.
Speed rating (letter code)
The speed rat ing letter code on the wheels ind icates the maximum
permissible road speeds =>
& in "Winter tires" on page 311.
P up to 93 mph (150 km/h)
Q up to 99 mph (158 km/h)
R up to 106 mph (170 km/h)
S up to 110 mph (180 km/h)
T up to 1 18 mp h (190 km/h)
U up to 124 mph (200 km/h)
H up to 130 mph (210 km/h)
V up to 149 mph (240 km/h)3>
Z over 149 mph (240 km/h)3>
W up to 168 mph (270 km/h)3>
Y up to 186 mph (298 km/h)3>
Your vehicle is normally factory equipped with t ires, which possess
excellent driving characterist ics and give you r A udi optimum driv ing
comfort. An electronic speed limiter=>
page 23 will normally prevent
your vehicle from going faster than the tire speed rating =>
&-
U.S. DOT Tire Identification Number (TIN) and tire
manufacture date
This is the tire's "serial number". It begins with the letters "DOT" and
indicates that the tire mee ts all federal standa rds. The next two
numbers or letters indicate the plant where it was manufactured, and
the last four numbers represent the week and year of manufacture .
For example, the numbers 2210 mean that the tire was produced in
3
l For tires w ith a maxim um speed capabi lity ove r 149 mph (240 km/h), tire
manufacture rs sometimes use the letters "ZR."
Safety first
the 22nd week of 2010 . The other numbers are marketing codes that
may or may not be used by the tire manufacturer . This i nformation is
used to contact consumers if a tire defect requires a recall.
Audi Original tire
Tires with the identification "AO" or "RO" have been specially
matched w ith your Audi. We recommend using only these tires
because they meet the highest standards regard ing safety and
driv ing characteristics when used correct ly. Your authorized Audi
dealer will gladly provide you with more information .
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support . Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades=> page 310.
Maximum Permissible Inflation Pressure
Th is number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury. _,.
Vehicle care Technical data

Tires and wheels Ill
----------------
For example: Tread wear 200, Traction AA, Temperature 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
government test course .
For example, a tire graded 150 would wear one and one half (1 1/2)
times as well on the government 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 under controlled conditions on specified government test
surfaces of asphalt and concrete . A tire marked C may have poor trac­
tion 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 dissi­
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material 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 performance which all
passenger car tires must meet under 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 .
Safety first
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established 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 buildup and possible tire failure. •
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 tires
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 construction
type as the other tires on your vehicle.
If your vehicle is equipped with all-wheel drive*, this will improve
traction during winter driving,
even with the standard tires. However,
we strongly recommend that you always equip all four wheels on your
vehicle with correctly fitted winter tires or all-season tires, when
winter road conditions are expected. This also improves the vehicle's
braking performance and reduces stopping distances.
Summer tires provide less grip 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 permitted
winter tire sizes. Use only radial winter tires. ..,_
Vehicle care Technical data

___ T_ ir_e_ s _ a_ n _ d_ w_ h_e_ e_ ls _______________________________________________ _
After changing a wheel, the torque must be checked as soon as
possible with a torque wrench -preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation. 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/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. 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 pres­
sures should be checked at least once a month and always before a
long trip=>
page 302, "Checking tire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire is
underinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle, we recommend that you observe the following precau­
tions:
• Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• 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, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others.
• Please also remember that, while these tires deliver responsive
handling, 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 originally 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 circumstances, you should equip your vehicle with
all-season or winter tires, which offer better traction under those
conditions. We suggest you use the recommended snow or all-season
tires specified for your vehicle, or their equivalent.
Refer to=>
page 311 for more detailed information regarding winter
tires. •

General notes '
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size .,

& WARNING
• If the tir e pres sure indicator appears in the instrument cluster
display, one or more of your tires i s significantly under-inflated.
Reduce your speed immediately and avoid any hard steering or
braking maneuvers. Stop as soon a s possible and check the tires
and their pressures . Inflate the tire pressure to the proper pres­
sure as indicated on the vehicle 's tire pressure label~
page 299.
Driving on a significantly under -inflated tire causes the tire to
overheat and can lead to tire failure. Under -inflation also is likely
to impair the vehicle's handling and stopping ability.
& WARNING (co ntinued )
• The driver is re sponsible for maintaining the correct tire pres­
sures . You must check the tire pres sures regularly .
• Under certain conditions (such as a sporty driving style , winter
conditions or unpaved roads) , the pressure monitor indicator may
be delayed.
• Ask your authorized Audi dealer if run-flat tires may be used on
your vehicle . Your vehicle registration becomes invalid if you u se
the se tires when not permitted. Damage to your vehicle or acci­
dents could also result.
