"P" indicates a tire for a passenger
vehicle. "T" indicates a tire desig­
nated for temporary use.
@ Nominal width

tween the sidewalls in millime­
ters. In general: the larger the number, the wider the tire.
@ Aspect ratio
Height/width ratio expressed as a
percentage .

R indicates a radial tire.
® Rim diameter
Size of the rim diameter in inches.
@ Load index and speed rating
The load index indicates the tire's
load-carrying capacity.
The speed rating indicates the
maximum permitted speed. Also

Glossary of tire and loading
terminology
Accessory weight
means the combined we ight (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 a re available as factory- in­
stalled equipment (whether in­
stalled or not) .
Aspect ratio
means the ratio of the height to
the width o f the tire in percent .
Numbers of 55 or lower indicate a
low s idewal l for improved steer­
ing response and better overall
handling on dry pavement.
Bead
means the part of the t ire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim .
Bead separation
means a breakdown of the bond
between components in the bead .
Wheels
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tir e pressure recom­
mended by the vehicle manufac ­
tu rer for a tire of a designated
size that has not been driven for
more than a couple of m iles (k ilo­
meters) at low speeds in the
three hour period before the t ire
pressure is measured or adjusted .
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
cluding the maximum capacity of
f u el, o il, and coolant, a ir cond i­
tioning and additional weight of
optio nal eq uipment .
Extra load tire
means a tire designed to operate
at higher loads and at higher in­
flat ion pressu res than the corre­
sponding standard tire . Extra load
tires may be ident ified as "X L",
"xl", "EXTRA LOAD", or "RF" on
the sidewall. .,.

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 acc ident. For the correct tightening specifi ­
cation, see ¢
page 192, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bo lts that fit the rim .
- Always have damaged r ims repa ired by an
authorized Audi dealer o r autho rized Aud i
Service Facility . Never repair or d isassemble
r ims yourself, because this inc reases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be­
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow .
... Use w inter t ires on all fo ur wheels .
... Only use winter t ires that are approve d for your
v ehicl e.
... Please note that the maximum permitted
speed may be lower with winter tires¢.&.
in
General information on page 166.
An au thor­
ized Audi dealer or author ized Audi Service Fa­
c ili ty can inform you about the maximum per­
mit ted speed for you r tir es .
... Check the tire press ure after installing w heels
¢ page 176.
The effec tiveness of winter tires is reduced great­
l y when the t read is worn down to a depth of
0 .1 57 in ( 4 mm). The char acter istics of win ter
tires a lso dec rease great ly as t he tire ages, re­
gardless of the remaining tread .
@) For the sake of the environment
Reinstall s umme r ti res at the a ppro pria te
t ime, bec ause they provide bet ter hand ling
Wh eel s
when roa ds a re free o f snow and ice . Summer
tires cause less road noise, tire wear and fue l
consumpt ion .
(D Tips
You can also use a ll season tires instead of
winter tires . Please note that in some coun ­
tries where winter tires are required , on ly
winter tires w it h the
& symbo l may be per­
mitted.
Snow chains
S now cha ins not only improve the drivi ng in win ­
te r road condit ions, but also the braking .
... On ly ins tall snow chains on the front wheels.
T his applies a lso to vehicles with a ll wheel
drive*.
... Check and correct the seating of the snow
chai ns after d riving a few feet, if necessary. Fol­
low the instr uctions from the manufac turer.
... Note the maximum permitted spee d when dr iv­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
U se fine-me sh snow chains . They must no t add
more than 0.53 inch (13. S mm) in height, incl ud­
ing t he chain lock .
You m ust remove the snow chains on roads with­
o ut snow . O therwise, you co uld impair d riving
abili ty and damage the t ires .
Use of snow c hains is only permitted with certa in
r im/tire comb inat io ns due to technical reasons .
C heck wi th an au thorized Audi dea ler or author­
ized Audi Service Facility to see if you may use
snow chains .
A WARNING
Using incor rect snow chains or installing snow
cha ins incor rect ly can resu lt in loss of veh icle
control, which increases the risk of an acci·
dent.
(D Note
Snow cha ins can damage the rims/whee l cov-
ers * if the chains come into direct contact

Tech nical data
Gross Axle Weight Rating
The G ross Ax le We ight Rating is the max imum
load that can be applied at each axle of the vehi ­
cle ¢& .
Vehicle capacity weight
The vehicle capacity we ight (max. load) is l isted
on the d river's side 8-p illar.
_& WARNING
- T he ac tual Gross Axle Weight Rating a t the
front and rear axles sho uld not exceed the
permissible weights, and their combination
must not exceed the Gross Veh icle Weight
Rating.
Dimensions
- Exceed ing permissible weight ratings can
result in vehicle damage, accidents and per­
sonal injury.
(D Note
- The vehicle capacity weight figures apply
when the load is d istr ibuted evenly in the
vehicle (passengers and luggage). When
t ransporting a heavy load in the luggage
compartment, carry the load as near to the
rea r axle as possib le so that the vehicle's
hand ling is not impaired .
- Do not exceed the max imum perm iss ible
axle loads or the maximum gross vehicle
we ight. Always remember that the ve hicle's
han dling will be affe cted by the extra load.
T herefore, a djust your speed acco rd ingly.
- Always observe lo cal regulations.
