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 .
The t ire pressure labe l is located on t he dr iver's side B-pilla r. The tire

• Incorrect tire pressures and /or underinflation can lead to a
s eriou s or fatal a ccident .
• Incor rect tire p ressu res and /or underinflation cause increased
tire wear and can affect the handling of the vehicle .
• Incorrect tire pressu res and /or underinflation can also lead to
s udden tire failur e, including a blowout and sudden deflation,
caus ing loss of vehicle cont rol. •
Checking tire pressure
The correct tire pressure for the tires ori ginally installed
on your vehicle is listed on the tire pressure la bel located
on driv er's side 8-pillar.
Th e recommended tire pressures a re on the tire press ure labe l and in
t he table~ page 299, "Cold tire infla tion pressure" . This means that
the pressure m ust be checked an d adju sted when the tire has not
bee n dr iven for more than a co uple of miles (kilometers) at low
speeds dur ing the previous three hours. Air in the tires expands w hen
the tire heats up as a resul t of inte rna l fr iction as it flexes in use. The
tire press ure is higher when the t ire has warmed up than when it is
"cold."
It is the inflation press ure i n a "cold" t ire that counts . Therefore, you
should never let air out of a warm tire to match "Co ld tire inflat ion
pressure" recommendat ions~
page 299 . The t ires would t hen be
underinflated and co uld fail sudden ly .
T he tire p ress ure label on your Audi lists the recommended co ld tire
inflation pressures for the new, or iginal equipment t ires that were on
your vehicle at t he time i t was man ufa cture d. For the location of t he
label~
page 299 , fig. 216.
Most tires lose a ir nat urally over time. They can a lso lose some a ir if
you d rive over a pot hole or hi t a curb while pa rking .
It is usua lly not possible to see whether the rad
ia l tires used today are underinflated
jus t by loo king at th em.
T herefore, be sure to check t ire pressures a t least once a month and
always before go ing on a long trip. Make sure to take the number of
peop le and the amoun t of lugg age i nto a ccount whe n ad justi ng tire
pressure for a trip -even one that you would not consider to be
" lo ng." See ~
page 303, "Ti res and vehicle lo ad lim its" fo r mo re
important informat ion.
Always use an accurate t ire pressure ga uge when check ing and
ad justing i nflat io n pressures . Check all of the tires and be sure not to
forget the s pare tire . If the press ure in any ti re is too hig h when the
t ire is "co ld," let ai r out of t he tire slowly with t he edge of the ti re
gauge and keep checki ng the press ure unt il yo u reach the press ure
that is co rrect for the load (p assenge rs a nd luggage) a nd kind of
driving yo u plan to do.
If the press ure in any t ire is too low , no te the difference between t he
pressure in the cold tire and the pressure you need and add the a ir
t ha t you need to reac h the co rrect pressure fo r the vehi cle load
(passengers a nd luggage) fo r the tires o n yo ur vehicle as listed on the
on your vehicle and in this man ual and the k ind of driving yo u plan to
do .
Never exceed the ma ximum inflation pressure listed on the tire
s idewall for any reason .
Remember that the vehicle manufacturer, not the t ire manufacturer,
determines the cor rec t tire p ress ure for the tires on your ve hicle.
It is important to chec k the tire pressu re whe n the t ires a re co ld.
• Read the required t ire pressure from the t ire pressure label. The
ti re press ure la bel is located on t he dr iver's s ide 8 -pilla r.
• Turn t he va lve stem cap counte r-clockw ise to remove it from th e

& 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 .

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 314.
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 299.
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 299) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located on driver's side B-pillar (~
page 299,
fig. 217) 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 307, fig. 220 . 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:
P245 / 45 R 17 99 H XL
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
245 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
17 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/S") Indicates that the tire has some mud and snow capa
bility
The tires could also have the information of direction of rotation
~page 295.

Tire manufacturing date
The manufacturing date is also indicated on the tire sidewall
(possibly on ly on the
inner s ide of the wheel):
"DOT ... 2210 ... " means, for example, that the tire was produced in
the 22nd week of 2010.
Speed rating (letter code)
The speed rat ing letter code on the wheels ind icates the maximum
permissible road speeds =>
& in "Winter tires" on page 311.

may or may not be used by the tire manufacturer . This i nformation is
used to contact consumers if a tire defect requires a recall.
Audi Original tire
Tires with the identification "AO" or "RO" have been specially
matched w ith your Audi. We recommend using only these tires
because they meet the highest standards regard ing safety and
driv ing characteristics when used correct ly. Your authorized Audi
dealer will gladly provide you with more information .
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support . Tire manufacturers also must indi
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury. _,.
Vehicle care Technical data
___ T_ ir_e_ s _ a_ n _ d_ w_ h_e_ e_ ls _______________________________________________ _
After changing a wheel, the torque must be checked as soon as
possible with a torque wrench -preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under a
variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
in the tire's size designation. The numeral represents the ratio of
the tire's sidewall height in relation to its tread width expressed in
percentage. Conventional tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres
sures should be checked at least once a month and always before a
long trip=>
page 302, "Checking tire pressure" .
What you can do to avoid tire and rim damage
Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire is
underinflated.
In order to minimize the occurrence of impact damage to the tires of
your vehicle, we recommend that you observe the following precau
tions:
• Always maintain recommended inflation pressures. Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes, deep gullies or ridges. The
impact from driving through or over such obstacles can damage your
tires. Impact with a curb may also cause damage to your tires. •
After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a damaged
tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventually cause tire failure. If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others.
• Please also remember that, while these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The low aspect ratio, ultra
high performance tires originally installed on your vehicle are
intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If you
drive under those circumstances, you should equip your vehicle with
all-season or winter tires, which offer better traction under those
conditions. We suggest you use the recommended snow or all-season
tires specified for your vehicle, or their equivalent.
Refer to=>
page 311 for more detailed information regarding winter
tires. •
