Tires and wheels
handling when in good condition and properly
inflated
¢
.&. .
We recommend that all wo rk on tires and
wheels be perfo rmed 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 technica l requirements for
installing or changing tires and rims.
Replacing tires and wheels
Tires should be rep laced at least in pairs and
not individually (for examp le both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitor ing system
¢ page 201.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
fo r your vehicle by Audi. Replacement tires
must always have the same load rating speci-
fication as the original equipment or approved
optional tires listed in the table ¢ page 193.
Audi-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold-
ing, driving characteristics, and safety of the
vehicle. The table (q page 193) 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 ( ¢ page 193, fig. 150) lists the speci-
f ications of the orig inal equipment tires in-
stalled on your veh icle at the time it was man-
ufactured .
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires q fig. 152. This information
identifies and describes the fundamental
characterist ics, the quality grade of the tire
and also provides a tire ident ificat ion number
fo r safety standard cert ificat ion and in case of
a recall.
Tire specifications
Knowledge of tire specifications makes it eas-
ier to choose the correct tires. Radial ti res
have the tire specifications marked on the
sidewa ll , for examp le:
P235 / 35 R 19 91 Y
This conta ins the following information :
P
Indicates the tire is for passenger cars
235
Nominal tire width in mm of the tire
from sidewall edge to sidewall edge. In
general, the larger the number, the wider
the tire
35
Height/w idt h ratio in percent (aspect ra-
t io)
R
Tire construct ion: Radial
19
Rim diameter code (in inches)
91
Load rating code
Y
Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF") indicates
t hat t he t ire is a"Reinforced" or an "Extra
Load" tire
M+S (or "M/5") I ndicates that the ti re has
some mud and snow capability
The tires could also have the information of
direction of rotat ion q page 189.
Tire manufacturing date
The manufact ur ing date is also indicated on
the tire sidewall (possibly only on the inner
side of the wheel):
"DOT ... 2213 ... "means, for examp le, that
the tire was produced in the 22nd week of
2013.
Speed rating (letter code)
The speed rating letter code on the whee ls in-
dicates the maximum permissible road speeds
q
.&.
in Winter tires on page 204 .
p
up to 93 mph (150 km/h)
Q
up to 99 mph (158 km/h)
R
