SECTION 13: WHEELS, HUBS AND TIRES
When tire pressures are increased to account
for higher vehicle weight, the TPMS set point
need to be increased accordingly.
 Vehicles not equipped with BERU TPMS
The condition and pressure of the tires can
greatly affect both useful tire life and road safety.
At regular intervals, verify the tire pressures. Use
an accurate tire pressure gauge when checking
inflation pressures. Never exceed the maximum
inflation pressure specified on each tire.
NOTE
Inflation pressure should be checked when
tires are cold. Cold tire inflation pressure can
be measured when a vehicle has not been
driven for at least 3 hours or less than 1 mile
(1.6 km). Driving, even for a short distance,
causes tires to heat up and air pressure to
increase. Check inflation pressure on all tires
(including the spare tire) using an accurate tire
gauge.
NOTE
The recommended tire inflation pressures are
given in the applicable documents supplied
with the vehicle. In addition, cold tire inflation
pressures are listed on the Department of
Transport's certification plate, affixed on the
panel behind the driver's seat for H3 series
vehicles and on the left side control panel for
X3 series vehicles. For special tire selection, a
"PREVOST COACH
SPECIFICATION" chart is supplied with the
vehicle and is affixed on the left wall near the
driver's seat. Remember, tire inflation pressure
must be adjusted according to vehicle loading
- see table in "Coach Final Record"
CAUTION
These tire pressures are established in
accordance with the maximum allowable load
on each axle. A
recommended if the axle load is less than the
above specifications. Weigh vehicle fully
loaded and pressurize according to tire
manufacturer's recommendations. For other
tire and wheel specifications, see Prevost tire
pressure tabulation in "Coach Final Record".

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).
WARNING
Incorrect tire pressures cause increased tire
wear and adversely affect road holding of the
vehicle, which may lead to loss of vehicle
control.
