FIGURE 39: TIRE INFLATION
CAUTION
Never bleed air from hot tires as tires will then
be under inflated. Use an accurate tire gauge
to check pressures (Do not kick tires as an
inflation check. This is an unreliable method).
FIGURE 40: TIRE LIFE / INFLATION PRESSURE
WARNING
Recommended tire inflation pressures and
maximum allowable loads apply to speeds up
to 65 mph (105 km/h). Do not drive vehicle at
a higher speed than
above the posted speed limit.
WARNING
All tires on the same axle should always be
inflated to the same pressure. There should
not be a difference in pressure between right
and left tires on the same axle.
Incorrect tire pressure
wear and adversely affect road holding of the
vehicle, which may lead to loss of vehicle
control.
11.2 TIRE MATCHING
Unmatched tires on drive axle will cause tire
wear and scuffing, as well as possible damage
to the drive unit. Consequently, It is
recommended that tires be matched within 1/8"
(3 mm) of the same rolling radius.
It is recommended that all tires on coach be of
the same type.
