Special characteristics of winter tires

112n
Choosing the right tire
BMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. While "all-season"
tires (M+S designation) provide better
winter traction than summer tires with
the load ratings H, V, W, Y and ZR, they
generally do not achieve the perfor-
mance of winter tires.
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.
Never exceed the maximum speed
approved for your specific winter
tires.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire inflation
pressure
When the tread wears to a depth of less
than 0.16 in (4 mm) there is a substan-
tial reduction in the tire's ability to pro-
vide adequate traction under winter
driving conditions. To ensure continued
safety, tires with this amount of tread
wear should always 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 wheels/tires.

Snow chains

*
The use of BMW narrow-link snow
chains on winter tires is approved only
in pairs and only on the rear wheels.
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.
It is not possible to mount snow
chains with 18-inch wheels and
tires.<
