Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop. Over load ing
can no t on ly lead to loss of vehi cle contro l,
but can also damage important pa rts of the
ve hicle and can lead to sudden tire failure, in
cluding a blowout and sudd en deflation that
can cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making s ure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle . These
load limits are techn ically referred to as the
ve hicle's
Gross Veh icle W eight Rat ing
(" GVWR ").
T he "GVWR" incl udes the we ight of the basic
vehicle, all f actory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus maximum load . T he maximum load includes
the number of passengers that the vehicle is in tended to carry ("seating capacity") with a n
assumed weig ht of 150 lbs . (68 kg) for e ach
passenger at a des igna ted seat ing pos ition
and the tota l we ight of any l uggage in the ve
h icle. If you tow a trailer, the weight of the
tra iler hitch and the tong ue weight of the
loaded trailer must be included as part of the
ve hicle load . T
he
Gro ss Axle We ight Rating ("GAWR") is
the maximum load that can be applied at each
of the veh icle's two axles .
T he Gross Vehicle Weigh t Rat ing and the
G ross Ax le Weight Rating are listed on the
safety comp liance sticker label located either
on the dr iver's s ide B-pillar or on the ins ide of
the fuel fi ller flap . Audi has
4 seating pos i
t ions, 2 in the front and 2 in the rear for to tal
seat ing capac ity of 4 . Each seating position
has a seat belt ¢
page 154, Safety belts.
The fact that there is an upper limit to yo ur
vehicle 's Gross Vehicle Weight Rating means
that the total weight of whatever is being car ried in the vehicle ( includ ing t he weight of a
t railer hitch and the tongue weight of the
l oaded tra ile r) is lim ited. The more passen
gers in the vehicle or passengers w ho are
heavier tha n t he standard we ights assumed
mean that less weight can be carried as lug
gage.

A WARNING
-Overloading a vehicle can cause loss of ve-
h icle contro l, a crash or other accident, se
rious pe rsonal injury, and even death .
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in
crease the risk of the loss of vehicle con
trol.
- The b rakes on a vehicle that has been
overloaded may not be abl e to stop the
veh icle w it hi n a safe distance .
- Tires on a vehicle that has been overload
ed can fail s udden ly, incl uding a blowo ut
a nd sud den defla tion, causing loss of
con trol an d a crash.
- Always make sure that the total load be
i n g tr anspor ted - incl ud ing t he weight o f
a trailer hitch and the tongue we igh t of a
~
loaded traile r - does not make the
vehicle heavi er than the vehicle's G ross
Vehicle Weight Rat ing.
Determining correct load limit
Use the example below to cal
culate the total weight of the
passengers and luggage or oth
er things that you plan to trans
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi
cle's placard (tire inflation
pressure label)
¢ page 256 ,
fig. 210 .
2. Determine the combined
weight of the drive r and pa s
sengers that will be riding in
your vehicle.
3 . Subtract the combined
weight of the driver and pas
sengers from
" XXX " kilo
grams or
"XXX " pounds
shown on the sticker
¢page 256 , fig. 210.
4. The resulting figure equals
the available amount of car-
Tires and wheels 261
go and luggage load capaci
ty. For exampl e, if the
"XXX"
amount equal s 1400 lbs.
and there will be five 150
lb s. passengers in your vehi
c le, the amount of available
c argo and lugga ge load ca
pacity is 650 lb s. (1400-7 50
(5
X 150) = 650 lbs .)
5. Dete rmine the combined
weight of luggage and cargo being loaded on the vehi cle .
That weight may not safely exceed the available cargo
and luggage load capa city
cal culated in Step
4.
6 . If your vehi cle will be towing
a trailer , load from your trail
er will be transferred to your
vehicle. Consult this manual
to determine how this re duce s the available cargo
and luggage load capacity of
your vehicle .

262 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv
ing style.

_____ __,.J)
Fig. 213 Rotating t ires for more even wear
Tread Wear Indicator (TWI)
The origina l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
¢
fig . 212 running across the tread. Depend
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn tires must be replaced .
Different figures may apply in other countries
¢ & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
¢ page 258.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota
tion intervals. Please remember the follow
ing:
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Ma intenance and Warranty Booklet .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown¢
fig. 213.
-Extra care must be taken when rotating di-
rection-specific tires¢
page 279.
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal
anced, resulting in vibrations you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impairing the safety of the vehi
cle. If tires show excessive wear, have the
whee l alignment checked by an authorized
Audi dealer or qualif ied workshop.
All wheel drive
Vehicles with quattro ® must a lways have tires
of the same size, construction and tread type.

Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
R eplacing t ires and whe els
Tires sho uld be rep laced at least in pairs and
not individua lly (for examp le both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system*
¢page 270.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement t ires
must always have the same load rating speci
fication as the original equipment or approved
optional tires listed in the table
c:> page 256.
Aud i-approved specification ti res are specially

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 295.
_&. 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.

Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified

What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom
mend that you observe the following p reca u
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •
•
2 70 T ire s and wheel s
- Drive carefu lly 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 neares t
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2 ,000 miles (3,000
km) for damage and wear . Damage is not al
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu
ally cause t ire failu re. If you be lieve that a
t ire may have been damaged, replace the
t ire as soon as poss ible.
- T hese tires may wea r more quick ly than oth
ers.
- Please also remember that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re no ise than

All ti res are des igned for certa in pu rposes.
The low aspect ratio, u ltra high performance
tires originally installed on your vehicle are in
tended for max imum dry and wet road per
formance and handling . They are not suitable
for cold, snowy or icy weather condit ions. If
you dr ive under those circumstances, you
should equip your vehicle with all-season or

Tire pressure
monitoring system
(l) General notes
App lies to vehicles: with tire pressure monitoring system
Each tire , includ ing the spare (if provided),
should be checked month ly when cold and in- flated to the inflation pressure recommended
by the vehicle manufact urer on the vehicle
placard or tire inflation pressure labe l. (If your
vehicle has tires of a different si ze than the
s ize indicated on the vehicle placard or tire in
flat io n pressure labe l, you shou ld determine
the proper t ire inflation pressu re for those
tires) .
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low tire
pressure te lltale when one or more of your
t ir es is significantly under-inflated. Acco rding
ly, when the low tire pressure telltale i llumi
nates, yo u shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure . Driving on a significantly un
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al
so reduces fuel effic iency and tire tread life,
and may affect the vehicle's hand ling and
stopp ing ability .
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv
er 's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to tr igger illum inat ion of the
T PMS low tire p ressu re tellta le.
Your vehicle has also been equipped with a
T PMS malfunction ind icator to ind icate when
the system is not operating prope rly . T he
T PMS ma lfunction indicator is combined w ith
t h e low tire pressure te lltale . When the sys
tem detects a malfunction , the telltale will
flash for approximately one min ute and then
remain continuously illuminated. This se
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists .
When the malfunction indicator is illuminat ed , the system may not be ab le to detect or
s ignal low tire pressure as intended. TPMS
malfunctions may occur for a var iety of rea
sons, including the installa tion of replace
ment o r alternate tires or wheels on the vehi
cle that p revent the TPMS from functioning
properly. Always check the TPMS malfunction
te lltale a fter rep lacing o ne or more tires o r .,.
wheels on your vehicle to ensure that the re
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly .
