Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least apprec iated and most abused pa rts of a moto r
vehicle. Tires are, however, one of the most important parts of a
veh icle, parti cularly conside ring the comparative ly small patch of
rubber on eac h tire that assu res that all- important co ntact between
you , your ve hicle and the road .
Ma inta in ing t he correct t ire pressu re, making s ure that your veh icle
and i ts tires do not have to carry more weight than they can safely
hand le, avoid ing damage from road ha za rds and reg ula rly inspect ing
tires for damage incl ud ing c uts, s lashes irregular wea r and overall
condi tion are the mos t important th ings that you can do to help avoi d
sudden tire fa ilure includ ing t read separation and blowouts .
Avoiding damage
If you have to drive over a curb or sim ilar obstacle, drive very s lowly
and as close as poss ible at a right angle to the cu rb .
Always keep chemicals including grease, oil , gasoline and bra ke fl uid
o ff the t ires .
Inspect the ti res regularly for damage (cuts, crac ks o r bl ist ers, e tc .).
Remove any foreign bodies embed ded in the trea ds.
Storing tires
M ar k tires when yo u remove t hem to indica te the d irect ion of rota ­
tion . This ens ures yo u to be able to mo unt them co rrectly whe n you
re insta ll them.
Wh en r emoved, t he wheels or tires s hould be sto red in a c ool, dry and
preferably da rk p lace. Sto
re tires in a ver tica l pos it ion if they a re not mounted on rims, in a
hor izonta l position if they are mo unted on r ims.
New tires
N ew tires have to be bro ken in~ & .
Th e tread dep th of new tires may v ary, ac cor ding to t he type an d
make of t ire and the tread pattern.
Hidden damage
Dama ge to t ires and rims is often not readi ly visible . If yo u notice
unusu al v ib rat ion o r the veh icle pulls to one sid e, t his may i ndicate
that one of the tires has been damaged. The tires must be c hecke d
i m medi ately by an a uthor ized A udi deale r or quali fied w or ksh op .
Unidirectional tires
A u nidirectional tire can be identified by arrows on the sidewall, that
point in the d irect io n the tire is des igned to rotate. Yo u m ust follow
t he s peci fied dire ction of ro tation . T his is nece ssary so th at t hese
tires can develop the ir optimum c haracter istics regarding gr ip, road
noise, we ar and hy dropl aning res istance. For more informa tion
~page 341 .
& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, drive with special care for the first 350 miles (560 km) .
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries. Have worn or damaged tires
replaced immediately. .,_

& WARNING (co ntinued )
• Tires age even if they are not be ing used and can fail suddenly ,
e specially at high speeds . Tires that are more than 6 year s old can
only be used in an emergency and then with special care and at low
s peed .

----------------
sure label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and tires that were on your
vehicle at the time it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the
vehicle at maximum load, you must increase the tire pressures to
those specified for maximum vehicle load~& .
Bear in mind that the tire pressure monitoring system* can only
mon itor the tire pressures you have stored . The system does not
recognize the load condition of your vehicle.
Th e effectiveness of the tire pressure monitoring system* will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum load~.&, . See the
illustration
~ page 310, fig. 2 52 for the locat ion of the label
either on dr iver's side B-pillar or inside the fuel filler flap (color of the
actual label and exact location on the vehicle will vary slightly) .
Note that the following tab le is accurate at the time of going to press
and is subject to change. In the event of discrepancies , the tire pres­
sure label (On USA vehicles, the tire pressure label is located on the
dr ive r's side B -pillar . On Canada veh icles, the tire pressure label is
located either on the dr iver's s ide B-pillar or inside the fue l f ill er flap)
always takes precedence.

The correct tire pressure for the spare wheel is located on a label
ei ther on the driver 's s ide B- pillar o r inside the f uel fille r flap .
Beca use techn ica l changes may be made to vehicle equipment during
the model year, always compare the tire size designation o n the tire
pressure labe l on yo ur vehi cle w it h the tires on your ve hicle. Make
sure that the tire size information on the ve hicle labe l is the same as
t he s ize of the tires on the vehicle. This is especia lly im portant if the
vehicle belongs to someone e lse or you boug ht the vehicle w it h
different r ims/ tires or you bo ugh t the vehicle as a prev iously owne d
veh icle .
Remember, your safety and that of your passengers also depends on
ma king sure that load limits are not exceeded. Vehicle load includes
everybody and everything in an d on the vehicle . These load limits are
t echnically refer red to as the veh icle's G ross Ve hicle Weig ht Ra ting
("GVWR"). The Gross Axle Weight Rating ("GAWR") is the max imum
load that ca n be applied at ea ch of the vehi cle's two axles. The G ross
Vehicle Weight Rating and the Gross Ax le Weight Rating are listed on
t he safety compliance sticke r label lo cated ei ther on the d river 's side
B-pil lar or o n the inside of the fuel filler flap. T he tire pressure label
on yo ur A udi lists the maximum comb ined weight o f all of the occu -pa

& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carry ing more weight than your vehicle was designed to carry
will prevent the vehicle from handling prope rly and increase the
ri sk of a lo ss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicl e within a safe distance.
• Tires on a vehicle that ha s been overloaded can fail suddenly
causing lo ss of control and a crash .
• Always make sure that the total load being transported -
i ncluding the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle 's Gro ss Vehicle Weight Rating .

& WARNING
• Incorr ect tire pressures and /or underinflation can lead to a
s erious or fatal accident .
• Incor rect tire pressures and /or unde rinflation cause increased
tire wear and can aff ect the handling of the vehicle .
• Incorrect tire pressures and /or underinflation can also lead to
sudden tire failure , including a blowout and sudden deflation,
caus ing loss of vehicle cont rol. •
Checking tire pressure
The correct tire pressure for the tires orig in a lly installed
on your vehicle is listed on the tire pressure label located
either on driver 's sid e 8-pillar or inside the fuel filler flap.
The recommended tire pressures a re on the tire p ressure labe l and in
t he table => page 310, "Cold tire infla tion pressure ".This means that
the pressure must be chec ked and adjusted when the tire has not
bee n dr iven for more tha n a coup le of m iles (k ilomete rs) at low
speeds dur ing t he previous three ho urs . Air in t he tires expands when
t he tire hea ts up as a r esu lt of in te rna l fr ic tion as it flexes in use. The
tire pressure is higher when the tire has warmed up than when it is
" ld "
co .
It is the inflation pressu re in a "cold" ti re that counts. Therefore, yo u
sho uld never let air out of a warm tire to matc h "Cold tire inflation
pressure" recommendations=>
page 310. The t ires would then be
underinflated and co uld fail sudden ly.
Th e tire press ure label on your Audi lists the re comme nded cold t ire
inflation pressures at max imum capacity for t he new, origina l equip­
ment tire s that were on yo ur vehi cle at t he time it was m anufactu red .
For the location of the label=>
page 310 , fig. 252.
M ost tires lose air nat urally
over time. They can also lose some air if
you d rive
over a potho le or hi t a curb while pa rking. It is usually not
Safety first
poss ible to see whether the radial t ires used today are underinflated
ju st by loo king at th em.
Th erefore, be sure to check t ire pressures a t least once a month and
always before going on a long trip. Make sure to take the n umber of
people a nd t he amount of luggage into account whe n ad justi ng tire
pressure for a tr ip -
even one that you would not consider to be
" long. " See =>
page 314, "Ti res and vehicle load limits" fo r more
important information.
Always use an acc urate t ire pressure ga uge when chec king and
adjust ing inf lation press ures. Check all of the tires and be sure not to
forget the spare tire . If the press ure in any tire is too hig h when the
t ir e is "cold," let air out of the t ire s lowly w it h the edge of the t ire
gauge and keep chec king the pressure u nti l yo u reach the pressure
t ha t is co rre ct for the load (passenge rs an d luggage) a nd kind of
dr iv ing you plan to do.
If the pressure in any ti re is too low, note t he difference betwee n th e
pressure in the co ld tire and the pressure you need and add the a ir
tha t you need to reach the correct p ressu re fo r th e ve hicle load
(passengers a nd luggage) fo r th e tires on yo ur vehicle as listed on the
on your vehicle and in this man ua l and the kind of driving you p lan to
do .
Never e xceed the max imum inflation pressure l isted on the tire
s idewall for any reason.
Remember that the vehicle manufacture r, not the t ire manufacturer,
de termines the correct tire press ure for the t ires on your vehicle.
It is i mport ant to che ck the t ire pressure when t he ti res a re cold.
• Read the required t ire pressure from the t ire pressure label. On
US A veh icles, the tire pressu re labe l is loca ted on the d river's si de B ­
pillar . On Canada vehicles, the tire pressure label is located either on
t he drive r's side B-pillar or inside the fuel fille r flap.
• Turn the
valve stem cap counter -clockw ise to remove it from the
tire
valve.
• Place the air press ure gauge on the valve. ..,.

& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, los s of control, collision, serious personal injury or even
death.
• When the warning symbol appears in the instrument
cluster , stop and inspect the tires.
• Incorrect tire pressure and/or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The dr iver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
& WARNING (co ntinued )
• Only when all tires on the vehicle are filled to the correct pres­
sure, the tire pressure monitoring* system can work correctly .
• The use of incorrect tire pressure values can lead to accidents or
other damage. Therefore it is essential that the driver observe the
specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation, sudden tire failure and loss
of control.
• Excessive speed and/overloading can cause heat build-up,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest service station
to check the tire pressure and add ai r as required.
