Wheel and tire combinations The right choice Use only wheels and tires approved by
BMW for the corresponding 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 116.
The correct wheel-tire combina-
tion affects different systems that
otherwise will not function properly,
e.g. ABS, DSC.
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 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 to112 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 187 mph (300 km/h)
ZR= over 150 mph (240 km/h) e.g.
Nominal width

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. e.g.
Rim width

Code letter for
flange type
Symbol for full-drop

Rim diameter in inches

safe and approves them. Consult your BMW center for more information.

Snow chains
*
It is not possible to mount snow chains
on 18 and 19-inch wheels.
Deactivate the tire pressure
control (RDW) when using snow
chains. The snow chains can lead to
malfunction warnings and undetected
losses in pressure.
