How to Check
Use a good quality pocket-type gauge to check
tire pressure. You cannot tell if your tires are
properly inflated simply by looking at them.
Radial tires may look properly inflated even
when they are under‐inflated. Check the tire's
inflation pressure when the tires are cold.
Cold means your vehicle has been sitting for
at least three hours or driven no more than
1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gauge firmly onto the valve to get a
pressure measurem ent. 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 you reach the recommended
amount.
If you overfill the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re‐check the tire pressure with the tire gauge.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Professional Vehicle
The proper inflation of the tires on your
professional vehicle depends on the type of tires
on it.
.
If your vehicle has P235/60R17 size tires, the
cold inflation pressure is 41 psi (284 kPa).
.
If your vehicle has LT235/60R17E 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's side of the vehicle.
If the final stage manufacturer's label is
not present, the coach‐buil der should be
consulted. 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.
Operation at inflation pressures below this
recommendation may cause your tires to become
overloaded.
