Rotating wheels between axles
Warning
Rotating tires between the axles on vehicles
with different tire sizes or rim sizes on the front
and rear axles can cause damage to the tires
and the vehicle. There is a risk of accident. Do
not rotate the tires between the axles on vehi‐
cles with different tire sizes or rim sizes on the
front and rear axles.
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated in pairs be‐
tween the axles to achieve even wear. Further in‐
formation is available from a dealer's service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure and
correct, if needed.

Wheels and tires
General information
The wheels consist of tires that are self-support‐
ing, to a limited degree, and possibly special
rims.
The reinforcement of the sidewall allows the tire
to remain drivable to a restricted degree in the
event of a tire pressure loss.
Follow the instructions for continued driving with
a flat tire.
Safety information
Warning
The vehicle handles differently when a run-flat
tire has insufficient or no tire pressure; for in‐
stance, reduced lane stability when braking,
braking distances are longer and the self-steer‐
ing properties will change. There is a risk of ac‐
cident. Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
Identification
The tires are marked on the tire sidewall with
Run-flat System Component RSC.
Repairing a flat tire
