Tire replacement Uniform Tire Quality GradingQuality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Tread wear 200 Traction AA
Temperature A
Use only tires with emergency
driving characteristics as there is
no spare tire available if you get a flat.
For further information, refer to
page 135.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 1200 indicates that the tire was
manufactured in week 12 of 2000.
BMW recommends the replacement of
all tires when the tires are no more than
6 years old, even if a tire life of 10 years
is possible.

Wheel and tire combinations The right choice Use only BMW-approved tires with
emergency driving characteristics.
Refer to page 103.
Due to the maximum speeds this vehi-
cle can reach, the use of specific brands
and sizes is mandatory. Consult any
BMW center for details. Comply with
local/national regulations.
The correct wheel/tire combinaton
affects different sytems, such as
ABS, ATC, DSC and RDW. The function
of these systems is impaired if improper
wheel/tire combinations are used.
For this reason, use only tires made by
the same manufacturer that have the
same tread configuration and possess
emergency driving characteristics. And
after a flat tire, for instance, restore the
approved wheel-tire combination as
soon as possible.<
Codes on tires and wheels The tire codes will aid you in selecting
the correct tire.
Codes on radial tires:
The speed rating indicates the approved
maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = up to 186 mph (300 km/h)
ZR = over 150 mph (240 km/h) For example:
Nominal width
in mm
Aspect ratio in X
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
245/45 R 18 96 W
Winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes stamped on light-alloy wheels:
Protect tire valves from dirt by using
screw-on valve stem caps. Dirt in the
valves frequently leads to slow leaks.
Tires with emergency driving character-
istics also possess an additional identi-
fication mark that varies by manufac-
turer, e. g.:
Bridgestone RFT
Dunlop DSST
Goodyear EMT
Michelin ZP For example:
Rim width
in inches
Code letter for
flange type
Symbol for full-drop
center rim
Rim diameter in inches
