Tire Rotation - Chevrolet Silverado 4500HD 2022 Manual

308 Vehicle Care
Check the condition of the tires for
abnormal wear patterns and proper
inflation pressures. Cut or broken tire
casings must be repaired or replaced.
Check the tread depth and tire inflation.
Check to see if the tread is evenly
worn. Minimum tread depth is 3 mm
(4/32 in) on steering tires. Look for cuts
or other damage to the tread or
sidewalls. Check for missing, broken,
or damaged valve cap and stem.
Check that the dual wheels, if equipped,
are evenly separated, and that the tires
are not touching one another.
Tires should be inspected for the
following conditions. If any are present,
the tire should be removed and
repaired, retreaded, or scrapped as the
condition indicates.
Any blister, bump, or raised portion
anywhere on the surface of the tire
tread or sidewall (other than a bump
made by a repair). These indicate the
start of internal separation.
Any cut that reaches to the belt or
ply cords or any cut that is large
enough to grow in size and depth.
Any nail or puncturing object.
If any stone or object is held by a
tread groove and is starting to drill
into the tread base, remove the
object.
Proper tire inflation, toe-in adjustment,
loads, and road speeds are important
factors governing tire life, steering ease,
maneuverability, fuel economy, and ride
quality.

Tire Rotation

Tires should be rotated every 12 000 km
(7,500 mi). See Maintenance Schedule
0 330.
Tires are rotated to achieve a uniform
wear for all tires. The first rotation is
the most important.
Anytime unusual wear is noticed, rotate
the tires as soon as possible, check for
proper tire inflation pressure, and check
for damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel alignment.
See When It Is Time for New Tires 0 310
and Wheel Replacement 0 312.
Dual Tire Rotation
When the vehicle is new, or whenever a
wheel, wheel stud, or wheel lug nut is
replaced or serviced, check the wheel
lug nut torque after 160, 1 600, and
10 000 km (100, 1,000, and 6,000 mi) of
driving. For proper torque and wheel
lug nut tightening information, see
Wheel Nut Torque under Capacities
and Specifications 0 371.
The outer tire on a dual wheel setup
generally wears faster than the inner
tire. Tires last longer and wear more
evenly if they are rotated. See Tire
Inspection 0 307 and
Tire Rotation 0 308. Also see
Maintenance Schedule 0 330.
