Tire Pressure - Chevrolet Silverado 4500HD 2022 Owner's Manual

Warning
To prevent property damage,
personal injury, and/or death, do not
mount tube-type tires on tubeless
wheels.
Warning
This vehicle may be equipped with
high-pressure steel-reinforced sidewall
tires. Specialized training and
equipment are required for servicing
high-pressure steel-reinforced sidewall
tires, including inflating, deflating,
installing, removing, mounting or
re-seating the tire on the wheel. To
avoid personal injury, death or
property damage, only qualified
dealers or service providers with
appropriate equipment should service
these tires. For inflating, always
make sure the tire and wheel
assembly is securely fastened to the
vehicle or placed in safety cage, use

a clip-on chuck air hose extension
and stand at least 12 feet away to
the side of the tire.

Tire Pressure

To prevent property damage,
personal injury, and/or death, for
field maintenance, only inflate and
load tires to the maximum of the
least-rated tire on the axle. Due to
tire manufacturers re-marking tires to
conform to the Sl (metric) system,
tires marked with old and new loads
or inflation pressures could be placed
on the same vehicle.
Maintaining the correct amount of air
pressure is a very important
maintenance practice to ensure safe
vehicle operation and long life for the
tires.

Warning
Vehicle Care
Failure to maintain correct inflation
pressure may result in sudden tire
destruction, improper vehicle handling,
and may cause rapid and irregular tire
wear. Therefore, inflation pressures
should be checked daily and always
before long-distance trips.
Underinflation
Do not allow tires to become
underinflated. Increased flexing due to
underinflation causes heat buildup
within the tire components. This leads
to reduced strength, breakdown of the
rubber compounds and possible
separation of the tire components (such
as ply and tread separation and reduced
retreadability).
Underinflation is also the primary cause
of blowouts. In addition, low inflation
causes an increase in rolling resistance.
This results in reduced fuel mileage, a
loss in tread life, and uneven wear due
to increased tread movement. To
determine proper inflation, refer to the
