Wheel and tire combinations

The right choice

Use only tires approved by BMW.

Refer to the information beginning on

page 128.

Due to the high speeds this vehicle can

reach, the use of specific brands, spec-

ifications and sizes is mandatory. Con-

sult any BMW center for details.

Comply with local/national regulations.

The correct wheel-tire combina-

tion affects different systems, e.g.

ABS, ATC

* and DSC, whose function

would otherwise be impaired if im-

proper wheel-tire combinations are

used.

For this reason, use only tires of the

same brand and tread pattern. In the

event of a flat tire, for example, remount

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.

The codes on radial tires:

The speed rating indicates the ap-

proved 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 = over 167 mph (270 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)

225/50 R 1692W

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.

For example:

Rim width

in inches

Code letter for

flange type

Symbol for full-drop

center rim

Rim diameter in inches

Hump on the 2 rim shoulders
