® Mud and snow capability
"M/S" or "M+S" indicates the tire
has characteristics that make it
suitab le for driving on mud and
snow .
& indicates a winter t ire .
@ Compos ition 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 materia ls
used in the tire . These include
steel, nylon, polyester and other
materials .
@ Maximum permitted load
This number indicates the maxi
mum load in k ilograms and
pounds that the tire can carry.

Glossary of tire and loading
terminology
Accessory weight
means the comb ined we ight (in
excess of those standard items
which may be replaced) o f auto
matic tra nsmission , power steer
ing , power brakes , power wi n
dows, power seats , radio , and
heater, to the extent that these
items a re available as facto ry-in
stalled equipment (whet her in
stalled or not).
Aspect ratio
means the rat io of the height to
the width o f the tire in pe rcent.
Numbe rs of 55 or lower indicate a
low sidewa ll for imp roved steer
ing response and better overa ll
handling on dry pavement .

Winter tires
Winte r ti res s ignificantly improve the veh icle's
handling when driving in winter condit ions. Be
cause of the ir construction (width, compound,
tread pattern), summer tires provide less trac
tion o n ice and snow.
,.. Use w inter t ires on all fo ur wheels.
,.. Only use winter t ires that are approved for your
vehicle.
,.. Please note that the maximum permitted
speed may be lower with winter tires
9 &, . An
authorized Audi dealer or authorized Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires.
,.. Check the tire press ure after installing wheels
9page 228.
The effectiveness of winter tires is reduced great
ly when the tread is worn down to a depth of
0 .1 57 inch (4 mm). The character istics of winter
tires a lso dec rease great ly as the tire ages, re
ga rdless of the remaining tread.
_& WARNING
- Never drive faster than the maxim um per
mitted speed for your tires. This cou ld cause
the tires to heat up too much . Th is increases
the risk of an accident because it can cause
the tire to burst.
- Always adapt your dr iv ing to the road and
traff ic 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 ti res at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer tires cause less road noise, t ire wear and fuel
consumption.
You ca n also use all season tires instead of
w inter t ires. Please note that in some coun
tries where w inter t ires are required, only
w inter t ires with the
& symbol may be per
m itted.

Snow chains
Snow chains improve traction in the snow .
,.. On ly install snow chains on the front wheels.
,.. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol
low the instruct ions from the manufacturer.
,.. Note the maximum permitted speed when dr iv
ing wit h snow chains. Do not exceed 30 mph
(SO km/h) .
Snow cha ins not o nly improve the
driving in win
te r road condit ions, but also the
braking.
Use of snow chains is only permitted with certa in
rim/tire comb inat ions due to technical reasons.
Check with an authorized Audi dealer or author
ized Audi Service Facili ty to see if you may use
snow c ha ins.
You must remove the chains when driving on roads that are
free of snow . When roads are free
of snow, snow chai ns can impa ir handling and
damage the tires, and the chains will qu ic kl y be
dest royed.
_& WARNING ~
Using incorrect snow chains or ins tall ing snow
chains incorrect ly can resu lt in loss of veh icle
control, which increases the risk of a n acci
dent.
(D 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.
- Using snow c hains that add more than 0.4
inch ( 10.5 mm) of height can severely dam
age the whee l housings and other vehicle
components.
- Do not insta ll and use snow chains if there is
a malfunction in the adapt ive a ir suspen
sion*, because the vehicle he ight will be
very low. If you drive with snow chains any
way, the wheel housings and other vehicle
components can be seve rely damaged.

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
tio tires. These tires have been thoroughly tested
and been selected specifically for your model fo r
thei r supe rb perfo rmance, road feel and handling
unde r a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re de tails.
The low aspect ratio of these t ires is indicated by
a nume ra l of
55 or less in the tire's size desig na
tion . The nume ra l rep resents the rat io of t he
tire 's sidewall he igh t in relat io n t o it s tread w idth
e xpresse d in percen tage. Convention al ti res have
a height/w idth ratio o f 60 o r more .
The performance of low -aspect-ratio tires is par
ticularly sensitive to improper inflation pres
sure. It is therefore important that low a spect
ratio tires are inflated to the specified pre ssure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
be checked at le ast once a month and alwa ys
before a long trip¢
page 228.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, curbs, gullies or
ridges on the road, pa rt icu la rly if the t ire is un
de rinflated.
In order to minimize the occurrence of impact
damage to the t ires of your ve hicle, we recom
mend that you observe the fo llow ing precau
tions:
- Always maintain recommended inflation pres
su res . Check your tire pressure every 2,000
miles (3,000 km) and add air if necessary .
- Drive caref ully on roads with potho les, deep
gul lies or r idges . The impact from drivi ng
through or over s uch obstacles can damage
you r tires. Im pact with a cu rb may also cause
damage to you r tires .
234
-After any impact, immed iate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire as
soon as possible.
- Ins pect 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 a ir and
underinfla tion, w hich could even tua lly cause
tire fa ilure . If yo u be lieve that a tire may have
been damaged, replace the tire as soon as pos
sible.
- These tires may wear mo re quickly than others .
- Please also remember that, while t hese tires
delive r responsive hand ling, they may ride less
comforta bly and make mo re noise than o ther
choi ces.
Reduced performance in winter/cold season
conditions
A ll ti res are des igned for certain purposes. The

o rigina lly ins talled on your veh icle are inten ded
f o r m ax imu m dr y and wet ro ad perfo rma nce and
handling . They a re not sui table for co ld, snowy or
i cy weather conditions . If yo u drive under those
c ir cu mstances, you should equip yo ur vehicle
with all-season o r winter tires, which offer better
tract ion under t hose conditions. We suggest you
use the recommended snow or a ll-season tires
spec ified for your vehicle, o r th e ir equiva le nt.

Emergency assistance
-Passengers must not remain in the vehicle
when it is jacked up.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- Make sure jack posit ion 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
Do not lift the vehicle by the sill. Position the
vehicle jack only at the designated lifting
points on the sill. Otherwise, your vehicle will
be damaged.
@ Tips
The vehicle jack mode* switches off automati
cally at speeds
above 6 mph (10 km/h).
