ing properties and the handling characteris‐
tics.
#
Avoid excessively low tire pressure.
Tire pressure which is too low can cause:

Tire pressure which is too high can cause:
R
Increased braking distance
R
Impaired handling characteristics

WARNING Risk of accident due to repea‐
ted pressure drop in the tires
The wheels, valves or tires could be dam‐
aged.
Too low a tire pressure can lead to the tires
bursting.
#
Examine the tires for foreign objects.
#
Check whether the tire has a puncture
or the valve has a leak.
