Irregular Wear: If irregular wear is present, check the axle alignment,
tire pressure, wheel balancing, shock and suspension component
condition, and wheel bearing end play.
This condition not only shortens tire life, but also adversely affects the
handling of your vehicle, which is dangerous.
Rotating tires from one wheel position to another is an often-used way to
even out many types of irregular wear or to avoid it altogether. Some of
the more effective tire rotation programs are:
• You can rotate steer tires that have developed some type of irregular
wear pattern to drive axles if using rib tires on all wheel positions.
Applying steer tires to a drive position often cleans them. You can
move them back to the steer axles or run out to re-tread stage on the
rear axle.
• Another rotation possibility for fleets with rib tires in all wheel
positions is to break in the new steer tires in the drive axle positions,
then move them to steer axles. This wears away tread rubber
relatively quickly in the early life of a tire when it is most likely to
develop an unusual wear pattern.
• You can place drive axle tires on the other end of the same axle to
reverse the direction of rotation. This is often helpful if a heel and
toe or alternate lug wear pattern has developed.
You can help minimize irregular wear by:
• Using the right inflation pressure for the load being carried.
• Maintaining proper front wheel alignment, especially toe-in, to
specifications.
• Maintaining proper tire and wheel balance.
• Maintaining shock absorbers and suspension components.
Use of Tire Chains
See the chain manufacturer's recommendation for correct tire chain
usage, installation and removal.
WHEELS
General Information
Note: Remember to replace the wheel air valves when replacing the road
tires at the end of their useful lives.
Inspect, lubricate and adjust wheel bearings at regular intervals. This is
especially important if operating in deep sand, mud or water. See the
Capacities and Specifications chapter.
Mount wheel balance weights on the dome-side of the wheel only. Failure
to do so may result in loss of wheel weight or damage to brakes or
wheels.
