Tire pressure generally refers to t he amo unt of a ir i n a tire tha t it
needs it to do its job and safe ly carry the comb ined load of t he entire
vehicle and its contents . Tire p ressure is measured in kilopasca ls
(kPa), the inte rnationa l measur ing unit and in poun ds per squar e in ch
(PSI). Tire press ure is based in part on the ve hicle 's design and load
limit -the greatest a mount of weight that the vehi cle can c arry safe ly
and the tire s ize. The proper tire pressure is frequently refer red to as
the "re commen ded cold t ire inflation p ressure. " Air in t he tires
expands when the tire heats up because of internal friction when it
flexes in use. T he tire press ure is hig her w hen the tir e h as warme d up
than whe n it is "cold." It is the inflation pressure in a "cold" tire that
c o unts. The refo re, you sho uld never let air o ut of a warm t ire to
match "cold ti re inflation pressure " recommendations . The t ires
wou ld then be under in flated and could fail s uddenly.

Ma intain ing prope r tire pressure is one o f the most importa nt things
you can do to he lp avoid sudde n tir e fa il u re . Under inflated tires are a
majo r ca use of sudden tire fa ilure . Keeping t ires at the rig ht pressure
is a lso important for safe and responsive vehicl e ha nd ling , traction,
braki ng an d load ca rryi ng.
Tire pressures are particularly impo rtant
when the vehicle is being driven at higher speed s, and then espe·
cially when heav ily loaded even within the permissible load ·
carrying capacities approved for your vehicle .
The recommended tire pressures for your Audi depend on the kind of
t ires on your vehicle and the num be r of passengers and/or amou nt o f
luggage you will be tra nspo rt ing .

& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure , loss 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 driver 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.
• 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 e ssential that the driver observe the
Safety first
& WARNING (co ntinued )
specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pres sure 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 re sulting 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 air as required .

Tire service Life
The servi ce life of tires depends on a lot of different
things including proper installation and balancing,
correct tir e pressure and driving style.

Marks on the t ire sidewall (for examp le "TWI " or other symbols) indi­
cate the positions of the tread wea r indicators . Worn t ires must be
replaced. Differe nt figu res may apply in other countries ~ & .
Tire pressure
Incorrect tire pressure causes premature wea r and can cause sudden
tire blow-o ut. Fo r th is reason, tire pressu re must be checked at least
once a month~
page 300.
Driv ing style
Driving fast aro und curves, heavy acceleration and hard b raking
increase tire wear .
Rotating tires for more even wear
For all four tires o n your ve hicle to have the same se rvice life, we
recommend that the fron t and rear t ires are rot ated according to the
tire manufact urer's suggested tire rotat ion intervals . Please
remember the fo llow ing :
• Tir e ro tat ion inte rvals may d iffe r from the vehicle serv ice intervals
out lined in your Maintenance and Warranty Booklet .
• The longer one tire is used in one locat ion on the vehicle, the more
it wears at certain points; therefore, we recommend that you follow
the t ire manufacture r's sugges ted tire rotation interva ls .
• Vehicles with front-whee l drive experience more tread wea r on the
front wheels compa red to a ll-wheel dr ive (quattro ®).
• Please ro ta te tires as shown~ fig. 219 .
• Extra care must be taken when rotating direction -specific t ires
~ page 323 .
Wheel balancing
The wheels on new vehicles are balanced. However, var ious si tuatio ns
dur ing everyday driving can cause them to become unbalanced,
resu lting in v ibr ations yo u can us ua lly fee l throug h the stee rin g
w heel.
Unbalanced whee ls mus t be rebalanced to avoid excessive wea r on
steeri ng, suspension and tires . A wheel must also be rebalanced
when a new tire is installed.

Incorrect wheel alignment
In correct whee l al ignme nt can ca use excessive tir e wea r, impairing
th e sa fety o f the vehicl e. If t ires show excessive w ear, hav e the w heel
alignment checked by a n authorized A udi dea ler or qualifie d work­
shop.
All Wheel Drive
Vehicles wi th quattro® must always have tires of the same size ,
con st ruct ion an d tread type . For details see~
page 246.
& WARNING
Sudden tire failure can lead to los s of control, a cra sh and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires 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 t ire damage, such as
grease , oil, gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially 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 speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failu re and loss of vehicle control. •

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. ..,_

Tires and wheels -_______________ _____.Effll
than the size indicated on the vehicle placard or tire inflation pressure
label , you sho uld determine the proper tire infla tion pressure fo r
those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressu re monitoring sys tem (TPMS) that illuminates a low tire pres ­
sure telltale when one o r more of your t ires is s ignificantly under­
inflated. Accord ingly, when the low tire pressure tellta le illumi nates,
you should stop and check your tires as soon as possib le, and inflate
them to the proper p ress ure. D riving on a sign ificantly under-inflated
tire causes the tire to overheat and can lead to tire fa ilure . Under­
inflation also reduces f uel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability .
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the d river's responsibility to mainta in correct tire
pressure, even if under-inflation has not reached the level to trigger
ill umination of the TPMS low tire press ure te lltale.
Your vehicle has also been equipped w ith a TPMS malfunction indi­
cato r to indica te when the system is not operating properly . The
TP MS ma lf u nction indicator is combined with the low tire p ress ure
telltale. When the system detects a malfunct ion, the telltale will
fl ash for approximate ly one minute and then rema in continuously
illuminated. This sequence will continue upon subsequent vehicle
sta rt-ups as long as the malfunction exists.
When the ma lfunction indicator is illum inated, the system may not
be able to de tect or signa l low ti re pressure as intended . TPMS
ma lfunctions may occur fo r a var iety of reaso ns, includ ing the instal­
lation of replacement o r alternate tires or wheels on the vehi cle that
prevent the T PMS from functioning properly . Always check the TPMS
ma lfunction tellta le after replacing one or more tires or whee ls on
yo ur vehicle to ensure that the replacement o r alte rnate t ires and
wheels allow the TPMS to continue to funct ion proper ly .•
