Special Features Of Winter Tires; Snow Chains - BMW 2002 Z8 Owner's Manual

Special features of winter tires

Choosing the right tire
For driving on winter roads, BMW
recommends winter tires – M+S radial
belted tires. Although all-season M+S
tires provide better winter traction than
standard summer tires with H, V, W, Y
and ZR speed ratings, they generally
fail to provide the same levels of perfor-
mance as standard snow tires in winter
driving.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
When selecting winter tires,
remember that you should never
mount anything other than Run-Flat
Tires, as your vehicle is not equipped
with a spare tire.
For further information, refer to
page 137.<
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which winter tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressure
Once the tread depth on winter tires is
less than 0.16 in/4 mm, they are no
longer suitable for winter road driving,
and in the interest of safety should be
replaced.
Comply with the specified tire inflation
pressures – and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.

Snow chains

*
The use of narrow-link BMW snow
chains is permissible in pairs only on
the rear wheels with winter tires with
tire size 245/45 R 18 96 H. Comply with
all manufacturer's safety precautions
when mounting the chains. Do not
exceed a speed of 30 mph/50 km/h
while driving with mounted snow
chains.
Do not activate the Flat Tire
Monitor when driving with snow
chains mounted. Malfunction warnings
and undetected losses in pressure are
a possibility when driving with snow
chains.
