9-8 WHEELS / TIRES
Air Pressure Inspection/Adjustment
Remove the valve cap.
Using tire air pressure gauge [A], measure the tire pressure when the
tires are cold.
Adjust the tire air pressure to suit track conditions and rider prefer-
ence, but do not stray too far from the recommended pressure.
When the track is wet, muddy, sandy or slip-
pery, reduce the tire pressure to increase
the tire tread surface on the ground.
When the track is pebbly or hard, increase
the tire pressure to prevent damage or punc-
tures, through the tires will skid more easily.
Tighten the valve cap securely.
As the tire tread wears down, the tire becomes more susceptible the
puncture and failure.
Remove any imbedded stones or other foreign particles from the
