® Mud and snow capability
"M/5" or "M+S" indicates the tire
has characteristics that make it
suitab le for driving on mud and
snow. ~ indicates a winter tire.
@ Composition of the tire cord
and materials
The number of plies indicates the
number of rubberized fabric lay­
ers in the tire . In general : the
more layers, the more weight a
tire can carry. Tire manufacturers
must also specify the materials
used in the tire. These include
steel, nylon, polyester and other materials.
@ Ma ximum permitted load
This number indicates the maxi­
mum load in kilograms and
pounds that the tire can carry.
@ Uniform tire quality grade
standards for treadwear,
traction and temperature resistance
T readwear, traction and tempera­
ture ranges ~
page 253.
@ Running direction
The arrows indicate the running
direction of unidirectional t ires.
You must always follow the speci-
238
fied running direction
~ page 264 .
(8) Maximum permitted
inflation pressure
This number indicates the maxi­
mum pressure to which a tire can
be inflated under normal operat­
ing condit ions.
Glossary of tire and loading
terminology
Accessory we ight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power steer­
ing, power brakes, power win­
dows, power seats, radio, and
heater, to the extent that these
items are available as factory -in ­
stalled equipment (whether in­
stalled or not).
Aspect rat io
means the rat io of the height to
the width of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer­
ing response and better overa ll
handling on dry pavement.

Wheels
Snow chains not only improve the driving in win­
ter road conditions, but also the broking.
Use of snow cha ins is o nly pe rm itted with certain
r im/t ire combinations due to tec hni cal reasons.
Check with an authorized Audi dealer or author­
ized repair faci lity to see if yo u may use snow
cha ins .
The snow c ha ins must have
low-profile lin ks and
m ust not be thicker than 0 .4 inch (10.S mm), in ­
cluding the lock.
You mus t remove the c hains whe n driving on
roads that are
free of snow. When roads are free
of snow, snow c hains can impair handling and
damage the tires, and the chains wi ll quickly be
destroyed .
_& WARNING
Using inco rrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
cont rol, which inc reases the risk of an acc i­
dent .
{CT) Note
-Snow cha ins can damage the rims/wheel
covers* if the chains come into d irect con­
tact with them . Remove the wheel cove rs*
first. Use coated snow chai ns.
- Using snow chains that add more than 0.4
inch (10.5 mm) of he ight can severely dam­
age the wheel hous ings and other vehicle
components.
- Do not i nstall and use snow chai ns if there is
a malfunct ion in the adaptive air suspen­
s io n, because the vehicle he igh t will be very
l ow. If you drive wi th snow ch ains anyw ay,
the wheel ho usings and other vehi cle com ­
ponen ts can be severely damaged .

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra ­
tio tires . These ti res have been tho roughly tested
252
and been sele cted specifica lly for your mode l for
their superb performance, road fee l and hand ling
u nder a var iety of dr iv ing cond it ions. Ask your au ­
thori zed Audi dea ler fo r more details.
The low aspect rat io o f these tires is indica ted by
a n umera l of
55 or less in the tire's size designa­
t ion . The n umera l represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Convent iona l tires have
a height/width ratio of 60 or more .
The performance of low-aspect-ratio tires is par­
t ic ularly sensitive to improper inflation pres ­
sure.
It is the refore important that low aspect
ratio tire s are inflated to the specified pressure
and that the inflation pressur e is regularly
checked and maintained . T ir e pressures should
b e c hec ked at l east on ce a month and alway s
befor e a long trip
¢ page 246.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
l y by impact with potholes, curbs, gullies or
ridges on the road, particularly if the tire is un­
derinflated.
In orde r to mi nimi ze the occur rence of impact
dam age to the tires of yo ur vehicle, we recom ­
mend tha t you observe the following preca u­
tions:
- Always ma intain recommended i nflation pres­
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith potholes, deep
gullies o r ridges. The impac t from dr iv ing
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your ti res.
-After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au­
thorized A udi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 mi les (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of air and
underinflation, wh ich could eventually cause
tire fa ilure . If you be lieve that a tire may have .,.

Emerg ency assis ta nce

actly
one locat ion for each wheel. The jack must
not be positioned at any other location

A WARNING
-
-Yo u or your passengers could be injured
wh ile chang ing a wheel if you do not follow
these safety precaut ions:
- Position the vehicle jack only at the desig­
nated lifting points and align the jack.
Otherw ise, the vehicle jack cou ld slip and
cause an injury if it does not have suffi­
cient hold on the vehicle.
- A soft or unstable s urface under the jack
may cause the vehicle to slip off the jack.
Always p rovide a firm base for the jack on
the ground. If necessary, use a sturdy
board under the jack.
- On hard, s lippery surface (such as tiles)
use a rubber mat or similar to prevent the
jack from slippi ng.
- T o help prevent injury to yo urself and yo ur
passenge rs:

- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- Make sure jack position is correct, adjust
as necessary and then continue to raise
the jack.
- Changes in temperature or load can affect
the height of the vehicle.
(D Note
