Tires and wheels
Use only BMW-approved tires.
Due to the high speeds which this vehi-
cle can reach, the use of specific
brands, specifications and dimensions
is mandatory. Consult any BMW
Retailer for details.
Observe national, provincial and state
regulations.
The tire codes will aid you in selecting
the correct tire. The essential data for
radial tires are as follows:
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 149 mph (240 km/h)
W = up to 167 mph (270 km/h)
ZR = over 149 mph (240 km/h)
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)
Use screw-on valve stem caps to
protect the tire valves against dirt. Dirt
in the valves frequently leads to slow
leaks.
