TIRE PRESSURE CHECK
1. Measure:
• Tire pressure
Out of specification → Adjust.
Standard tire pressure:
100 kPa (1.0 kgf/cm
• Check the tire while it is cold.
• Loose bead stoppers allow the tire to slip off
its position on the rim when the tire pressure
is low.
• A tilted tire valve stem indicates that the tire
slips off its position on the rim.
• If the tire valve stem is found tilted, the tire is
considered to be slipping off its position. Cor-
rect the tire position.
