Steps for Determining Correct Load Limit
1.Locate the statement "THE COMBINED WEIGHT OF OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehicle's placard (tire infla
tion pressure label) =>
page 249,
fig. 171.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo
grams or
"XXX" pounds shown on the
sticker =>
page 249, fig. 171.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will be five 150 lbs . passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5
X 150) = 650 lbs.)
Safety first
Tires and wheels -
5. Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer ,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the available cargo and luggage load capacity of your
vehicle.
- Check the tire sidewall(=>
page 257,
fig. 175) to determine the designated
load rating for a specific tire . •

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.

ma ke, there w ill be six to eight of them even Ly placed around the ti re.
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 252.
Driv ing style
Driving fast aro und curves, heavy accele ration 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 Warranty
& Maintenance 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~
page 256, fig. 174.
• Extra care must be taken when rotating direction -specific t ires
~ page 279 .
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 194.
& 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. •

The tires and rims are essential parts of the vehicle's design. The tires
and r ims approved by Audi are spec ially 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 facilit ies for disposing of the old tires.
Authorized Audi dea lers have the necessary information about tech
nical requirements for installing or chang in g ti res and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not ind ividually (for
example both front tires or both rear t ires together).
Be sure to read and heed the tir e pressure monitoring system*
information=>
page 264.
Always buy replacement radial tires that have the same specifications
as the tires approved for your veh icle by Audi . Replacement tires must
always have the same load rating specification as the original equip
ment or approved opt iona l tires listed in the table=>
page 249.
Audi-approved spec ification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road
holding, driv ing characteristics, and safety of the vehicle. The table (=>
page
249) lists specifications of the tires approved for the Aud i
models covered by your Owner's Literature.
The tire pressure label located either on driver's side B-p illar or inside
the fuel filler flap(=>
page 249, fig. 172) lists the specifications of
the original equipment tires installed on your ve hicle at the time it

Federal law requires tire manufact urers to place standardized infor
mation on the sidewall of all tires =>
page 2 5 7, fig. 17 5. This i nfor
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a t ire identification number
for safety standard certification and in case of a reca ll.
Tire specifications
Knowledge of tire specificat ions makes it easie r to choose the correct
tires. Rad ial tires have the tire specifications marked on the s idewall,

& WARNING (conti nu ed )
ev en though the damage cannot be seen that can lead to sudden
tire failure and lo ss of vehicl e control.
• All four wheels must be fitted with radial tires of the same
type, size (rolling circumference ) and the same tread patte rn .
Driving with different tires reduces vehicle handling and can lead
to a los s of control.
• If the spare t ire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with e xtra care. Refit the
normal road wheel as soon a s safely possible.
• Never drive faster than the maximum speed for which the ti res
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cau se 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 o ver or underinflated.
• For technical reasons it is not always possible to use wheels
from other vehicle s- in some cases not even wheels 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 , increa sing stopping distance s
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassis designed
for run flat tires and a factory-in stalled tire pres sure monitoring
sy stem* that indicates a loss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or accidents. Check with an
authorized Audi dealer or tire speciali st 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 .

Tread wear
The tread wear grade is a compa ra tive ra ting based on the wear rate
of the tire when tested unde r co ntrolled conditions on a specified
government test co urse.
For examp le, a tire g rade d 150 would wea r o ne and one half (1 1/2)
times as well on the government course as a tire graded 100.
Th e relat ive performance o f tires depends upon t he ac tual con ditions
o f their use, however , and may de pa rt s ig ni ficantly from the norm
due to variations in driv ing ha bits, service prac tices an d differences in
roa d characterist ics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band C. Those
grades represent the tire's ab ility to s to p on wet pavemen t as
meas ured under controlled condit ions o n spec ified governme nt test
s u rfaces of asphalt and conc rete. A tire mar ked C may have poo r trac
ti on perfo rma nce => & .
Temperature
The temperature grades are A (t he h ighest), B, a nd C, rep resenting
the t ire's resistance to the gene rat ion of heat and its ab ility to dissi
pate hea t when test ed unde r co ntro lled condi tions o n a spe cifi ed

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 e xcessive loading, either separately or in combination, can
c ause heat buildup and po ssible tire failure .•
Winter tires
W inter tires can improve vehicl e handling on snow and
ic e. A t temper atures belo w 45 °F (7 °C) we recommen d
ch angin g to win ter tires .
In some heavy snow areas , loca l gover nments may requ ire true
wi nte r o r "snow" t ires, those with very deep ly c ut trea d. These tires
should only be use d in pairs and be i nstalled on all fo ur w heels . Mak e
sure you purchase snow tires that are the same size a nd constr uction
t ype as the ot her tir es o n your ve hicle.
If your veh icle is eq uipped with all-wheel drive*, th is will improve
t raction during w inte r drivin g, eve n with t he standard tires . However,
we st rongly recomme nd that you a lways equi p all four w hee ls on your
vehicle with correctly fitte d winter t ires or a ll-season ti res, w hen
wi nter road conditions a re expe cte d. Thi s also improves the vehicle 's
bra king pe rformance and re duces stop ping distances.
S u mme r tir es pro vide less g rip on ice and snow .
Winter tires (snow tires) must always be fi tted on all fo ur whee ls .
Ask yo ur autho rized Audi deale r or qu alified wor kshop for permitted

& WARNING
Winter tires have ma ximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off. Never drive faster than the speed perm itted fo r
your specific winter tires . This will cause damage to the tire s
leading to an accident and serious personal injury to you and your
passengers.
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were des igned can cause ti re failure includ ing a
blowout and sudden deflation, lo ss of control, crashes and serious
personal injuries . Have worn or damaged tires replaced immedi
ately.
• Winter t ires have maximum speed rat ing that may be lower
than your vehicle's maximum speed .
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated.
& WARNING
Always adjust your driving to the road and traffic conditions.
Never let the good acceleration of the winter tires and all-wheel
drive tempt you into taking extra risks. Always remember :
• When braking , an all-wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions.
Use s ummer tires when weather co ndit io ns permit. They are qu ieter,
do not wear as quickly and reduce fuel consum ption .•
