place.
▷ Always protect tires against all contact with
oil, grease, and solvents.
▷ Do not leave tires in plastic bags.
▷ Remove dirt from wheels or tires.
Runflat tires
Principle
Run-flat tires permit continued driving under re‐
stricted conditions even in the event of a com‐
plete tire pressure loss.
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.
