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 per form­
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 m inimum required by law.
_&. WARNING
The traction grade assigned to this t ire is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering, hydrop lan ing o r peak traction
character istics .
_&. WARNING
The temperature grade for this t ire is es­
tablished for a ti re 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 tires shou ld
only be used in pa irs and be installed on all
four wheels. Make sure you pu rchase snow
tires that are the same size and const ruct ion
type as t he other tires on your ve hicle.
Your veh icle is equipped w ith all -wheel drive,
this will improve tract io n during w inte r dr iv­
in g, even with the standard tires. Howeve r, we
strongly recommend that you a lways eq uip a ll
four whee ls o n your ve hicle with correctly fit­
ted winter tires or all -season tires, when w in ­
ter road conditions a re expected. This also im-

reduces stopping dista nces.
Summe r ti res prov ide les s gr ip on i ce and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur whee ls.
Ask your authorized Audi dealer or qualified
workshop for permitted winter tire sizes. Use
o nl y rad ial winter t ires.
Winter tires lose their effectiveness whe n the
tread is worn down to a depth of0 .157 inch
(4 mm) .
Only drive w ith w inter t ires under w inter con­
dit ions. 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 replace­
ment wheel¢
page 260 .
Please always remember that winter tires may
have a lower speed rating t han the tires o rigi­
nally installed on your vehicle at the time it
was manufactured. P lease see¢
page 263,
Speed rating (letter code)
for a listing of the
speed rating le tter codes and the max imum
speed at which the tires can be d rive n.
The speed rating letter code(¢
page 245) is
o n the side wall of the tire ¢
page 260.
_&. WARNING
Winter t ires have maximum speed limits
that may b e lower than yo ur vehicle's max­
imum speed. Always know the max imum
speed before dr iv ing off. Never dr ive faster
than the speed permitted for yo ur spe cific
win ter tires . This wi ll ca use damage to the
tires leading to an accident and ser ious
personal injury to you and your passen­
gers.
_&. WARNING
Driving faster than the maximum speed
for which the winter tires on your ve hicle
were designed can cause t ire failure in­
cluding a blowout and sudden d eflation,

268 Tires and wheels
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on your vehicle are rated.
A WARNING
Always adjust your driving to the road and traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle .
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used .
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10,5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q 0 . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
@ Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily .
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the vehicle.
(j) Tips
Where snow chains are mandatory on cer­
tain roads, this normally also applies to
vehicles with all-wheel drive .

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
~ page 296.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is

Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
ratio tires . These tires have been thoroughly
tested and been selected specifically for your model for their superb perfo rmance, road fee l
and hand ling u nder a variety of driving condi­
tions . Ask your au thorized Aud i dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or l ess in the tire's si ze
designation. The n umera l represents the ra tio
of the ti re's sidewall height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a height/width ratio of 60 or
more.

~ page 252 , Checking tire pressure.
What you c an do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes, curbs, gull ies

In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following p re ca u­
tions:
- Always ma inta in recommended inflation

Tire pressure indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 205 Display: underinflation warning
Fig. 206 Display: System malfunction
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­ ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru­
ment cluster with a warning symbol
rD] and a
message
c:> fig . 205.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and fu ll load pressure) or after changing or re­
placing a tire on your vehicle
c:> page272 . The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
c:>page247.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure

c:> page 272. If the indicator light
does not turn off or if it turns on shortly
thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
_& WARNING
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label<=:>
page 247 . 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 stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must check the tire pressures regularly.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a sp are t ire wi th a tread pattern
int ended fo r use in a specific dir ect ion
When us ing a spare tire w ith a tread patte rn
intended for use in a specific direction, please
note the following:
- The direction of rotation is marked by an ar­
row on the side of the tire.
- If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the t ire will not be able to
achieve its optimum performance character­
ist ics with rega rd to aquaplaning, noise and
wea r.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weather and
that you adjust your speed to matc h road
conditions.
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
possible to restore the handling advantages
of a unidirectiona l tire .
