138nWinter tires Snow chains*
Choosing the right tire BMW recommends winter tires – M+S
radial tires – for operation under
inclement winter driving conditions.
While so-called all-season tires with
M+S designation provide better winter
traction than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance 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.
Do not exceed specified maximum speeds Never exceed the maximum speed
for which the 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 Sports
Activity Vehicle center will be glad to
assist you with both their expertise and
the proper equipment for your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in/4 mm, and should thus
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.
Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. The use of narrow-link BMW
snow chains is approved only in pairs
on the rear wheels and only with the
following tire sizes.
BMW X5 4.6is: 255/55 R18
All other models: 235/65 R 17.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a maximum speed of
30 mph/50 km/h.
