BMW Z4 ROADSTER Owner's Manual page 277

General information
The wheels consist of tires that are self-sup-
porting to a limited degree and may also in-
clude special rims.
The reinforcement of the sidewall allows the
tire to remain drivable to a limited 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 runflat
tire has insufficient or no tire pressure; for
instance, reduced directional stability when
braking, braking distances are longer and the
self-steering properties will change. There is
a risk of accident. Drive moderately and do
not exceed a speed of 50 mph/80 km/h.
Identification
Runflat tires are labeled with a circular icon
containing the letters RSC marked on the tire
sidewall.

Repairing a flat tire
Safety precautions
▷ Park the vehicle as far away as possible
from passing traffic and on solid ground.
▷ Turn on the hazard warning system.
▷ Secure the vehicle against rolling away by
setting the parking brake.
▷ Turn the steering wheel until the front
wheels are in the straight-ahead position
and engage the steering wheel lock.
▷ Have all vehicle occupants get out and
make sure that they remain outside the
hazardous area such as behind a guardrail.
▷ If necessary, set up a warning triangle at an
appropriate distance.
Tire repair set
Principle
With the tire repair set, minor tire damage
can be sealed temporarily to enable continued
driving.
General information
▷ The filled in tire sealant closes the damage
from the inside when it hardens.
▷ Follow the instructions on using the tire re-
pair set found on the compressor and seal-
ant bottle.
▷ The use of a tire repair set can be ineffec-
tive if the tire puncture measures above ap-
prox. 0.16 in/4 mm.
▷ Do not remove foreign objects that have
penetrated the tire. Remove foreign objects
only when they are visibly protruding from
the tire.
▷ The compressor can be used to check the
tire inflation pressure.
