Tire pressure is affected by changes
in ambient temperature and altitude,
and so the tire pressure should be
checked and adjusted when your rid-
ing involves wide variations in tem-
perature or altitude.
A. Tire Pressure Gauge
MAINTENANCE AND ADJUSTMENT
Tire Air Pressure (when cold)
250 kPa (2.50 kgf/cm², 36 psi)
290 kPa (2.90 kgf/cm², 42 psi)
Tire Wear, Damage
As the tire tread wears down, the tire
becomes more susceptible to puncture
and failure. An accepted estimate is
that 90% of all tire failures occur during
the last 10% of tread life (90% worn).
So it is false economy and unsafe to
use the tires until they are bald.
In accordance with the Periodic
Maintenance Chart, measure the
depth of the tread with a depth
gauge, and replace any tire that
has worn down to the minimum al-
lowable tread depth.
