Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al
so damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas
sengers also depends on making
sure that load limits are not ex
ceeded. Vehicle load includes ev
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi cle's
Gross Vehicle Weight Rat
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in
stalled accessories, a full tank of
fuel, oil, coolant and other fluids ..,
217

Wheels
plus maximum load . The maxi
mum load includes the number of
passengers that the vehicle is in
tended to carry ("seat ing capaci
ty") with an assumed weight of
150 lbs. (68 kg) for each passen
ger at a designated seating posi
tion and the total weight of any luggage in the vehicle. If you tow
a trailer , the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ
ed as part of the vehicle load .
The
Gross Axle Weight Rating
( " GAWR") is the maximum load
that can be applied at each of the
vehicle 's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas
sengers in the vehicle or passen
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
218
are listed on the safety compli
ance sticker label located on the
driver's side B-pillar
~ page 215,
fig . 169 .
& WARNING ~ -
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per
sonal 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 sud
denly, including a blowout and
sudden deflation, causing loss
of control and a crash .
-Always make sure that the to tal load being transported -
including the weight of a trail
er 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 calcu
late the total weight of the pas
sengers and luggage or other
things that you plan to transport
so that you can ma ke sure that
your vehicle will not be overload ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's pla card
(tire inflation pre ssure l abel)
¢ page 215 , fig. 169.
2 . Determine the combined
weight of the drive r and pas
s engers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
" XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 215 , fig. 169 .
4. The re sulting figure equals the
available amount of cargo and
luggage load capacity. For ex
ample, if the
" XXX" amount
equals 1400 lbs. and there will
Wheels
be five 1 SO lbs. pa ssengers in
your vehicle, the amount of available cargo and luggage load capacity i s 650 lb s.
(1400-750 (5 X 150) = 650
lbs.)
5. Determin e the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex
ceed the available cargo and luggage load capa city cal culat
ed in Step 4 .
6. If your vehi cle will be towing a
trailer, load from your trailer
will be transferred to your ve
hicle. Con sult thi s manual to
determine how this reduces
the available cargo and lug gage load capacity of your vehi
cle.
..,.Check the tire sidewall
(¢ page 205 , fig. 167) to deter
mine the designated load rating
for a specific tire.

and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi
cation, refer to ¢
page 22 7, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 215.
The effectiveness of winter tires is reduced great
ly when the tread is worn down to a depth of
0 .157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
220
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in height, includ
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.

of snow, snow chain s can imp air handling and
damage the t ires, and t he chains will quickly b e
destroyed.
A WARNING
Using incorrect snow chains or installing snow
chains incorrect ly can result in loss of vehicle
co ntrol, which increases the risk of an acc i
dent .
Snow chains can damage the r ims/wheel cov
ers* if the chains come into d irect contact
w ith them . Remove the wheel covers* first.
Use coated snow chains .

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
t io ti res. These t ires have been tho rough ly tested
a n d been se lected specifically fo r yo ur model for
t he ir superb performance, road feel and handling
under a variety o f driving conditions. Ask your au
thor ized Audi dealer for more details .
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire 's size designa
tion . The numera l represents the rat io o f the
tire's sidewall height in relat ion to its tread width
expressed in pe rc e ntage. Conventional t ir e s hav e
a height/w idth rat io of 60 or more.
The performan ce of low- aspect- ratio tire s is par
ticularl y sensiti ve to imp roper inflat ion pres
sure . It is therefore import ant that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and mainta ined . Tire pre ssure s shoul d
be checked at least once a month and alwa ys
befor e a long t rip
¢ page 215.
What you can do to avoid tire and rim
damag e
Low aspect rat io tires can be damaged more easi
ly by impact with potho les, curbs, gull ies or
Wh eel s
ridges on the road, particular ly if the tire is un
deri nflated.
In orde r to min imi ze the occurrence of imp act
damage to the tires of yo ur vehicle , we recom
mend that you observe the following preca u
tions:
- Always ma intain recommended inflat io n pres
sures. Check yo ur ti re pressure every 2,000
miles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith po tholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have th em inspected by th e nearest au
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect you r tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see . Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged , replace the tire as soon as pos
sib le.
- These tires may wear more quickly than others .
- Please also remember that, while these tires
delive r responsive ha ndling, they may ride less
comfortably a nd make more noise than other
choi ces.

Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
c::> page 205, fig. 167.
For example: Tread wear 200, Traction AA, Tem
perature
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 gov
ernment test course.
For example, a tire graded 150 would wear one
and one half (11/2) times as well on the govern
ment 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 un
der controlled conditions on specified govern
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction 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 dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
c::> .&. .
222
The grade C corresponds to a level of perform
ance which all passenger car tires must meet un
der 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.
A WARNING -
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor
nering, hydroplaning or peak traction charac
teristics.
A WARNING , ~ -
The temperature grade for this tire is estab
lished 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.
A WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat
ed.
Tire pressure monitoring system
(l) General notes
App lies to vehicles : wit h tire pressure mo nitori ng syste m
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la
bel, you should determine the proper tire infla
tion pressure for those tires) .
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
