Correct inflation
maximum stability, rider comfort and tire life.
Always check tire pressures before riding
when the tires are cold. Check tire pressures

Specification section for details of the correct
inflation pressures.
Warning
Incorrect tire inflation will cause abnormal
tread wear and instability problems that
may lead to loss of control and an accident.
Under-inflation may result in the tire
slipping on, or coming off the rim.
Over-inflation will cause instability and
accelerated tread wear.
Both conditions are dangerous as they may
cause loss of control leading to an accident.

becomes more susceptible to punctures and
failure. It is estimated that 90% of all tire
problems occur during the last 10% of tread
life (90% worn).
