Ma inta in ing p roper tire pressure is one of the most important th ings
you can do to he lp avoid sudden tire fa ilure. Underinflated tires are a
ma jo r ca use of sudden t ire failure. Keep ing t ires a t the right pressu re
is a lso important for safe and responsive vehicle handling, tract ion,
bra king and loa d ca rry ing .
Tire pre ssures are particularly important
when the vehicle is be ing dr iven at higher speeds, and then espe­
cially when he avily loaded even within the permi ssible load·
carr ying capacities approved for your veh icle.
Th e recommended tire pressures for your Audi depend on the kind of
tires on your vehicle and the number of passengers and/or amount of luggage you will be transporting.
O n USA veh icles, the tire pressure label is lo cated on the drive r's side
8-pillar. On Canada vehicles, the t ire pressure label is located either

T ir e pressure ge nera lly refers to the amount of air in a t ire that it
needs it to do its job and safely carry the combined load of the entire
veh icle and i ts conten ts. Tir e pressure is measured in kilopascals
(kPa), the international measur ing unit and in pounds per square inch
(PSI) . Tire press ure is based in part on the veh icle 's design and load
limit -the greatest amount of weight that the vehicle can carry safe ly
and the t ire size . The proper tire pressure is frequently referred to as
the "recommended cold t ire inflation pressure." Air in the tires
expands when the ti re hea ts up because of i nterna l fr iction when it
flexes in use. The ti re p ressu re is highe r when the t ire has wa rmed up
than when it is "cold ." It is the inflation pressure in a "co ld" tire that
co unts . Therefo re, you should never let air out of a warm tire to
match "cold tire inflation pressure" recommendations . The t ires
would then be under inflated and could fail suddenly.

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

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

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=>

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

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

& 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.

& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage
or other things that you plan to transport so
that you can make sure that your vehicle
will not be overloaded. .,_

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 320.
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 310.
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 310) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located either on driver's side B-pillar or inside
the fuel filler flap (=>
page 310, fig. 253) 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 318, fig. 256. 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:
255/45 R 18 99 H
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
255 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
18 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/5") Indicates that the tire has some mud and snow capa­
bility
The tires could also have the information of direction of rotation

& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to loss of cont rol, collision
and seriou s per sonal injury .
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original fa ctory-in stalled tires or other combination s that
have been specifically appro ved by the vehicle manufacturer.
• 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 u sed in an emergen cy and then with special care and at
lowe r speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged

tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type, size (rolling circumference ) and the same tr ead pattern.
Driving with different t ires reduces vehicle handling and can lead
to a lo ss of control.
• If the spare ti re is not the same as the tires that are mounted
on the vehicle - for example with w inter tires - only use the spare
tire fo r a sho rt pe riod of t ime and drive with extra care. Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s 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 technical reasons it is not always possible to use wheels
from other vehicles - in some c ases not even wheel s 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. Reduced airflow to
the brakes can them to overheat , increasing stopping distance s
and causing a collision.
• Run flat tires may only be u sed on vehicles th at were equipped
with them at the factory. The vehicle must have a chassis designed
fo r run flat tires and a factor y-in stalled tire pres sure monitoring
system* that indicates a loss of tire pre ssure. Incorrect use of run
flat tires can lead to vehicle damage or accident s. Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels. Mixing tire types is not permitted . ..,_
