Tire pressure
Tire pressure should be adjust to suit the road
surface condition of the circuit.
Under a rainy, muddy, sandy, or slippery
condition, the tire pressure should be lower
for a larger area of contact with the road sur-
face.
Under a stony or hard road condition, the tire
pressure should be higher to prevent a flat
tire.
Standard tire pressure:
100 kPa (1.0 kgf/cm2, 15 psi)
Extent of adjustment:
60 ~ 80 kPa
(0.6 ~ 0.8 kgf/cm
2, 9.0 ~ 12 psi)
Extent of adjustment:
100 ~ 120 kPa
(1.0 ~ 1.2 kgf/cm
