The tires and rims are essential parts of the
vehicle's design . The tires and rims approved
by Audi are specially matched to the charac-
ter istics 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
whee ls be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary special
tools and spare parts as well as the proper fa-
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary
information about technical requirements for
insta lling 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 mon itor ing system*

Always buy replacement radia l tires that have
the same specificat ions as the tires approved
for yo ur vehicle by Audi. Replacement tires
must always have the same load rating speci-
fication as the origina l equipment or approved
optiona l tires listed in the tab le¢ page 238 .
Audi-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important roadhold-
ing, driving characteristics, and safety of the
vehicle. The table
(c;,
page 238) lists specifica-
tions of the tires approved for the Audi mod-
els covered by your Owner's Literature .
The tire pressure label located on driver's side
B-pillar
(c;,
page 238, fig. 192) lists the speci-
fications of the original equipment tires in-
stalled on your vehicle at the time it was man -
ufactured .
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires co fig . 195 . This information
identifies and describes the fundamenta l
characteristics, the quality grade of the t ire
and also provides a tire identification number ..,.
