The tires and rims are essential parts of the vehicle's design . The tires
and rims approved by Audi are specially matched to the characteris-
tics of the vehicle and can make a major contribution to good road
holding and safe handling when in good condition and properly
inflated
~
& .
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer . They are familiar with recommended
proce-
dures and have the necessary special tools and spare parts as well as
the proper facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech-
nical requirements
for installing or changing tires and rims.
Replacing
tires
and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together) .
Be sure to read and heed the information to the tire pressure moni-
toring system ~ page 233.
Always buy replacement radial tires that have the same specifications
as the tires approved for your vehicle by Audi. Replacement tires must
always have the same load rating specification as the original equip -
ment or approved optional tires listed in the table ~ page 224.
Audi-approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road-
holding, driving characteristics,
and safety of the vehicle . The table
(~ page 224) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located on driver's side B-pillar (~ page 224,
fig. 146) lists the specifications of the original equipment tires
installed on your vehicle at the time it was manufactured.
Federal law requires tire manufacturers
to place standardized
infor-
mation on the sidewall of all tires~
page
231, fig . 149 . This infor-
mation identifies and describes the fundamental
characteristics,
the
quality grade of the tire and also provides a tire identification number
for safety standard certification and in case of a recall.
Tire specifications
Knowledge of tire specifications makes it easier to choose the correct
tires . Radial tires have the tire specifications marked on the sidewall,
for example:
P245 / 45 R 17 95 H
This contains the following information:
P
Indicates the tire is for passenger cars
245 Nominal tire width in mm of the tire from sidewall edge to side-
wall edge. In general, the larger the number, the wider the tire
45 Height/width
ratio in percent (aspect ratio)
R
Tire construction : Radial
17 Rim diameter code (in inches)
95 Load rating code
H
Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF") indicates that the tire is a"Rein-
forced" or an "Extra Load" tire
M+S (or "M/S") Indicates that the tire has some mud and snow capa-
bility
The tires could also have the information of direction of rotation
~ page
220.
