Honda CRF250F Owner's Manual Installation And Operation page 148

TYRES
To safely operate your motorcycle, the tyres
must be the proper type (off-road) and size,
in good condition with adequate tread, and
correctly inflated.
Using tyres that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or
killed.
Follow all instructions in this owner's
manual regarding tyre inflation and
maintenance.
Air Pressure
Properly inflated tyres provide the best
combination of handling, tread life, and
riding comfort. Generally, underinflated
tyres wear unevenly, adversely affect
handling, and are more likely to fail from
being overheated. Underinflated tyres can
also cause wheel damage in rocky terrain.
Overinflated tyres make your motorcycle
ride harshly, are more prone to damage
from surface hazards, and wear unevenly.
Make sure the valve stem caps are secure. If
necessary, install new caps.
