If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size, as 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, e.g. at an authorized
Mercedes-Benz Center.
