General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particular ly considering the comparative ly sma ll patch
of rubber on each tire that assures that all -important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regular ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overal l condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avo iding d am age
If you have to drive over a curb or similar obstacle, drive very slowly
and as close as possible at a right angle to the curb.
A lways keep chemica ls including grease, oil, gasoline and brake
flu id off the ti res .
I nspect the tires regularly for damage (cuts, cracks or blisters, etc .!.
Remove any foreign bodies embedded in the treads .
Storing tire s
Mark tires when you remove them to indicate the direction of rota ­
tion. This ensures you to be ab le to mount them correctly when you
reinstall them. When removed, the whee
ls or tires should be stored in a coo l, dry
and preferably dark place.
Store tires in a vertical position i f they are not mounted on r ims, in
a horizontal position if they are mounted on rims.
N ew tire s
New tires have to be broken in => &.
The tread depth of new tires may vary, according to the type and
make of tire and the tread pattern.
Hidd en d am ag e
Damage to tires and rims is often not readily visible . If you notice
unusua l vibration or the vehic le pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immediately by an author ized Audi dealer or qualified workshop .
Uni dir ection al tire s
A unidirect ional tire can be identified by arrows on the sidewa ll, that
point in the direction the tire is designed to rotate. You must fo llow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
=> page 298.
Rim s with bolted rim ring *
Light-alloy wheels with a bo lted rim ring consist of several parts .
These parts are screwed together with special bo lts, using a specific
technique. This ensures proper function, seal, safety, and true running of the wheel. For this reason, damaged rims shou ld be
replaced, and you should never repair or dismantle them
=> & .
Rim s with screw -on decorative co vers *
Light-a lloy whee ls can be furnished with interchangeab le decora -
tive covers that are mounted to the rim with se lf -locking bolts. ...

In correct wheel alignment
Inc orrect wheel alignment can cause excessive tire wea r, impairing
the saf ety of the vehicle . If tires s how excessive wear , have the
whee l alig nment chec ked by an autho rized A udi deale r or q ualif ied
workshop .
All Wheel Drive
Vehicles with quattro ® must always have tires of the same si ze ,
cons tructi on and tread type . For details see => page 218 .
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indi cators .
• E specially in wet and slick driving situations , a preferably large
profile depth of the tires is necessary , and an approximately
similar profile depth of the front and rear axle tire s.
• The diminished driving safety , caused by too small of a tire
profile , is negatively perceivable especially in handling , in danger
of hydroplaning when driving through deep puddles and ponds ,
when driving around curve s, and in braking behavior.
• Worn t ires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control.
• Always keep chemicals that can cause tire damage , such a s
grease , oil , gasoline and brake flu id away from tires.
• Tires age even if they are not being used and can fail suddenly ,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lowe r speeds.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old u sed tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and los s of vehicle control. •

warn you if it is necessa ry.
• T he battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
r ecommend us ing facto ry insta lled va lve stem caps. Ask you r autho ­
rized Audi dealer to replace lost va lve stem caps.
T he installation of rep lacement tires with steel cord body p lies in
t he tire sidewall may cause mal functi on of the tir e pressure mo ni­
toring system , and is not recommended (cord material information
in mo lded o n th e ti re sid ewa ll) .

& WARNING
• Using incorrect or unmatched tires and I or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always use t ires , rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fa il suddenly,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speed s.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tire s may have been damaged
even though the damage cannot be seen that can lead to sudden
tire f ailure and loss of vehicle control.
& W ARNING (continued )
• All four wheels mu st be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driv ing
with different tires redu ces vehicle h andling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for e xample with winter tire s - only u se the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
the ir rated speed can fail suddenly .
• Overloading tires cause heat build-up, sudden tire failure ,
including a blowout and sudden deflation and loss of control .
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicle s -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision.
• Run flat tire s may only be used on vehicle s that were equipped
with them at the fa ctory . The vehicle must have a cha ssis designed
for run flat tires and a factory -installed tire pressure monitoring
s ystem that indicate s a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
autho rized Audi dealer or t ire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used , they mu st
be installed on all four wheels . Mixing tire types is not permitted. .,

0 Not e
• For technical reasons, it is not genera lly possible to use the
wheel rims from other vehic les. 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 t ires), then
use the spare tire for a short period of time only and drive with extra
care. Rep lace the flat tire with the tire matching the others on your
vehic le as soon as possible.
• If you should put different wheels and tires on your vehic le (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatib le with the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed . For more information, contact your Aud i
dea ler.
0 Note
• When insta lling new tires, be carefu l not to damage the valves or
t ire pressure monitoring system* senso rs.
• Never drive without the va lve stem cap. The va lves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same t ime.
Dispose of old tires in accordance with the local requirements .•
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C Qua
lity grades can be found where applicable on the tire side wall
be tween tread shoulder and maximum section widt h =>
page 279,
fig. 21 1.
For example : Tread wear 200, Traction AA , Temperature A.
All passenger car tires must conform to Federa l Safety Require­
ments in addition to these grades.
Tre ad w ear
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under con trol led conditions on a specified
government test course.
F o r exam ple, a tire g raded 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 condi ­
tions of the ir use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differ ­
ences in road cha racteristics and c limate .
Tra ction
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
measu red under contro lled conditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance =>
/.1.
Temperatur e
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 contro lled conditions on a specified
indoor laboratory test wheel.
Sus tained high temperature can cause the material of the ti re to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=>
/.1.
The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle
Vehic le care

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
Safety Standard No. 109 . Grades Band A represent higher leve ls of
p er forma nce on th e laboratory test w hee l tha n the minim um
required by law .
& WARNING
The traction grade ass igned to this t ire is based on straight-ahead
braking traction tests , and does not include a cceleration ,
c ornering , hydroplaning or peak tra ction characterist ics .
& WARNING
The temperature grade for this tire is established fo r a tire that is
properly inflated and not overloaded. Excessive speed , underinfla­
tion, or exces sive loading , either separately or in combination , can
cause heat buildup and possible tire failure . •
Winter tires
Winter tires can improve veh icle ha ndl ing on sno w and
ic e. A t tem peratures belo w 45 °F (7
°C ) w e rec omm end
c ha ng ing to wint er tir e s.
In some heavy snow areas, local governments may require true
winte r or "snow" tire s, those wi th ve ry deeply cut tread. These tires
should only be used in pairs and be instal led on a ll four wheels .
M ake s ure you p urchase snow ti res that are the same size and
cons truct ion type as the o the r ti res on your v ehicle.
I f your vehic le is equipped with al l-wheel drive*, this will improve
t raction during w inter dr iving, even with the s tandard tires .
H owever, we strongly recommend that you a lways equ ip all four
whee ls on y our vehic le wi th correc tly fitted winte r tires or all-seas on
tires, when winter road conditions are expected. This also improves
th e ve hic le 's brak ing performance and red uces s to ppi ng d ista nce s.
Summer t ires p rov ide less gr ip o n ice and s now. Winter tires (snow tires) must a
lways be fitted on all four whee ls .
I f your veh icle is equipped with a ti re pre ssure monitoring system*,
compatible t ire pressure mon itoring sensors must be installed on
a ll four winte r tires for the system to function properly ~
page 281.
Ask your aut hori zed Audi dealer or quali fied wo rksho p for perm itte d
winter tire sizes . Use only radial winter tires.
Winter tires lose thei r effec tive nes s when the tread is wo rn down t o
a depth of 0.157 inch (4 mm).
On ly drive with winter tires unde r winter conditions. Summer tires

temperature is above 45 °F (7 °C) .
I f you have a flat tire, see n otes on s pa re whee l~
page 279.
Please a lways remember that w inte r tires may h ave a lowe r speed
rating than the tires original ly instal led on yo ur vehic le at the time
i t was manu fac tured. Please see~
page 281, "Speed rating (letter
code)" for a listing of the speed rating letter codes and the
m ax imum speed at wh ic h th e tir es ca n be d riven .
The speed rating letter code(~
page 270) is on the side wa ll of the
ti re ~
page 279.
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed . Always know the maximum speed
before driving off . Never drive faster than the speed permitted for
your specific winter tires . This will cause damage to the tires
leading to an accident and serious personal injury to you and your
pa ssengers.
& WARNING
Driving faster than the maximum speed for whi ch the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , los s of control , crashes and seriou s
