den acceleration ,aswell as drivin gover
obstacles (i.e. kerbs ,potholes), and driving
off-road. This is particularl ythe cas ew hen

The maximum permissibl edistanc ethat
can be driven in run-flat mod edepend sto
al arg eexten tont heloads placed on the
vehicle. It can be shorter due to high
speeds ,aheavyload, sudden acceleration
and/o rmanoeuvring, th eroads urfac econ-
dition ,outside temperature, etc. ,orfurther
if you drive carefully and conservatively.
