tires MERCEDES-BENZ B-CLASS 2012 Workshop Manual

Notes on the vehicle equipment – always
equip the vehicle with:
R
tires of the
same size on a given axle (left/
right)
R the same type of tires at a given time
(summer tires, winter tires, MOExtended
tires)
Exception: it is permissible to install a
different type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(Y page 281).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you
additionally equip your vehicle with a TIREFIT
kit if you mount tires that do not feature run-
flat properties, e.g. winter tires. A TIREFIT kit
may be obtained from a qualified specialist
workshop.
i The following pages contain information
on approved wheel rim and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the factory
as standard equipment or optional extras.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size. The size of the approved winter tires
may differ from the standard tires. This is
dependent on the model and the
equipment installed at the factory.
The tires and wheel rims, as well as further
information, can be obtained at a qualified
specialist workshop.
In the following table, the wheel/tire
combinations are assigned to the vehicle
models through variants, e.g. V1, V2 etc.: V1
