The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char-
acteristics of the vehicle and can make a major contribution to good
road holding and safe handl ing when in good condition and prop -
erly inflated =>& .
We recommend that al l work on tires and wheels be performed by
an authorized Audi dealer . They are familiar with recommended
procedures and have the necessary specia l too ls and spare parts as
we ll as the proper facilities for disposing of the old tires .
Authorized Audi dealers have the necessary information about tech -
nical requirements for insta lling or changing tires and rims .

Always buy replace ment radia l t ires tha t have the same specifica -

tires must always have the same load rating specification as the
original equipment or approved optional tires listed in the table

Audi-appr oved specificat ion tires are specially matched to your

P Indicates the tire is fo r passenger cars (where appl icab le)
235 Nominal tire width in mm of the tire from sidewall edge to side-
wa ll edge. In general, the larger the number, the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction: Radial
18 Rim diameter code (in inches)
95 Load rat ing code
V Speed rating letter code
XL (or " xi", "EXTRA LOAD" or " RF") indicates that the tire is a "Rein -
forced" or an "Extra Load" ti re
M +S (or "M/S") Indicates that the tire has some mud and snow capa -
