Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili-
"
8 l) Obey any applicable regulations in your
0 ~ country.
Wheels
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion ¢
fig. 2 70. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones¢ &.-
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires, install the tires from the rear axle ..,.

Wheels
on the front axle and vice versa.
This will allow the tires to have approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢ page 362.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are
hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
s ide, drive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.
.&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can increase the risk of an
accident because it has a nega­
tive effect on handling, driving
through curves, and braking, and because it increases the
340
risk of hydroplaning when driv­
ing through deep puddles.

-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much . This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a negative effect on driving and
braking behavior, which in­
creases the risk of an accident.

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 . Veh icle 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
Wheels
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating 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 A xle Weight Rating
(" GAWR ") is the maximum load
that can be applied at each of the
vehicle's two axles.
T he 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
trai ler) is lim ited. 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 .,.

Wheels
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar.
A 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 i ncrease the risk of the loss of
vehicle control.
-The brakes on a veh icle 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 b lowout and
sudden deflation, causing loss
of contro l and a crash.
-Always make sure that the to­ tal load being transported -i nc luding the weight of a tra il­
er hitch and the tongue
weight of a loaded trailer­
does not make the vehicle
h eavier than the vehicle's
Gross Vehicle Weight Rating.

Determining correct load
limit
Use the example below to calcu­
late the tota l weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be over load ­
ed.
Steps for Determining Correct Load Limit
1 . Locate the statement " TH E
COMBIN ED WE IGH T OF OCC U­
PANTS AND CARGO SHOU LD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehic le's placard
(tire inflation pressure label)
¢ page 340, fig . 272 .
2. Determine the combined
weight of the drive r and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢
page 340, fig. 272 .
4. The resu lting figure equa ls the
available amount of cargo and
luggage load capacity . For ex­
ample, if the "XXX" amount
eq uals 1400 lbs. and there will~

A WARNING
--
Wheel bo lts that are tightened or repaired in­
correct ly can become loose and resu lt in loss
of vehicle contro l, wh ich increases the risk of
an accident . For the cor rect tighten ing specifi­
cation, see <::>
page 362, Finishing .
-Always keep the wheel bolts and the
threads in the wheel h ub clean and free of
g rease .
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
author ized Audi dealer or author ized Audi
Serv ice Facility . Never repair or disassemb le
rims yo urself, because th is increases the r isk
of an acc ident.
Winter tires
Winter tires sign ifican tly imp rove the vehi cle's
handling when dr iv ing in winter conditions . B e­
ca use of their const ruct ion (w idth, compou nd,
tread pattern), summer tires provide less trac ­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. On ly use winter tires that a re app roved fo r yo ur

The effectiveness of w inter tires is reduced great­
ly when t he tread is wo rn down to a depth of
0.16 in (4 mm). The cha racter istics of w inte r
t ir es also decrease g reatly as the t ire ages, re ­
gard less o f th e rem aining t read.

tires cause less road noise, tire wear and fuel
consumption.
(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 with the
& symbol may be per­
mitted.
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking .
~ Only install snow chains on the front wheels.
~ Check and correct the seating of the snow
chains after driving a few feet, if necessary . Fol­
low the instructions from the manufacturer.
~ Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized 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 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with ­
out snow. Otherwise, you could impair driving
ability and damage the tires.
.&_ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
(LlJ) Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them. Remove the wheel covers*
first. Use coated snow chains.
- Do not install and use snow chains if there is
a malfunction in the air suspension*, be­
cause the vehicle height will be
very low. If
346
you drive with snow chains anyway, the
wheel housings and other vehicle compo­ nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch the offroad mode on
r=> page 143.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
Low -profile tires can become damaged more
quickly than standard tires when driving
over
large bumps, potholes, manhole covers, and
curbs . Therefore, it is particularly important to
maintain the correct tire pressure
r=.> page 340.
To reduce the risk of damage to the tires and
rims, drive
very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage . For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires .
Uniform tire quality grading
- Tread wear
- Traction AA ABC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
