Wheel and tire combinations

The right choice

Use only wheels and tires

approved by BMW for the corre-

sponding vehicle model, as otherwise

the tires may make contact with the

body as the result of tolerances despite

the same nominal size being used,

resulting in serious accidents. If non-

approved wheels and tires are used,

BMW cannot evaluate their suitability,

and therefore cannot be held liable for

driving safety.<

For wheel and tire specifications

approved by BMW, refer to page 150.

The correct wheel-tire combina-

tion affects different systems such

as ABS, ATC and DSC. The function of

these systems is impaired if improper

wheel-tire combinations are used.

For this reason, use only tires of the

same brand and tread pattern on the

vehicle and, for example, restore the

approved wheel-tire combination

following a flat tire as soon as

possible.<

Codes on the tires and wheels

The code on tires has the following

meaning.

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)

Example:

Nominal width

in mm

Aspect ratio in X

Belt rating code for

radial tires

Rim diameter in inches

Load rating

(not on ZR tires)

Speed rating

(before R on ZR tires)

235/65 R 17 104 H

All-season, all-terrain and 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 on light-alloy wheels:

Protect valve stems and valves from dirt

using screw-on valve stem caps. Dirt in

the valves frequently leads to slow

leaks.

Storage

Store tires in a cool, dry place,

protecting them against light when-

ever possible. Protect the tires against

contact with oil, grease and fuel.

Example:

Rim width

in inches

Code letter for

flange type

Symbol for full-drop

center rim

Rim diameter in inches

Special extended hump

on the 2 rim shoulders
