MOBILITY
Warning
Driving over curbs, road damage or other ob-
stacles can damage wheels, tires and chassis
components. Larger wheels have a smaller
tire cross-section. The smaller the tire cross-
section, the higher the risk of tire damage.
There may be a risk of accidents and risk of
damage to property. If possible, avoid driving
over curbs, road damage or other obstacles,
or drive over them slowly and carefully.
Exchanging wheels and
tires
Mounting and wheel balancing
Have the wheel mounted and balanced by an
authorized service center or another qualified
service center or repair shop.
Suitable wheels and tires
General information

tire combinations on the basis of the following
criteria:
▷ Tire size, e.g., tire width, aspect ratio.
▷ Wheel size, e.g., rim diameter, offset.
Ask an authorized service center or another
qualified service center or repair shop about
wheels and tires that are suitable for the vehi-
cle as well as special equipment.
