load carrying capacity. See
Vehicle Load Limits on
page 9‑10.
How the vehicle is loaded
affects vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry.
When to Check
Check your tires once a month
or more. Do not forget to check
the spare tire. If the vehicle has
a compact spare tire, it should
be at 420 kPa (60 psi). See
Compact Spare Tire on
page 10‑69 and Full-Size Spare
Tire on page 10‑70.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.
Recheck the tire pressure with
the tire gauge.
Return the valve caps on the
valve stems to prevent leaks
and keep out dirt and moisture.
Professional Vehicle
If the vehicle has P245/45R19 size
tires, the cold inflation pressure is
35 psi (241 kPa).
If the vehicle has 235/55R18 size
tires, the cold inflation pressure
depends on the vehicle mass and
should be determined by the vehicle
coach-builder. A Tire and Loading
Information label provided by the
final stage manufacturer should be
attached to the B-pillar on the driver
side of the vehicle. If the final stage
manufacturer's label is not present,
contact the coach-builder. Do not
use the tire pressures indicated on
the General Motors label. These tire
pressures are for the incomplete
vehicle and are not the correct tire
pressures for the completed
professional vehicle.
