TIRE MAINTENANCE
TIRE WEAR DIAGNOSTIC CHART
• Misalignment - from rough roads, pot holes,
excessive speeds and hitting curbs.
The wear pattern and tread life of tires involves many
variables that the user has control of, but does not
fall under faulty manufacture or design.
The following is a list of some causes supplied by
tire suppliers and axle manufacturers:
BASIC WHEEL TORQUE REQUIREMENTS (per mfg.)
Keep lug nuts properly tightened, check new unit before operation, after the first 10, 25, and again
at 50 miles. Check the torque weekly.

•
Tire Width - the wider the tire for flotation, the more
uneven the tire wear.
• Tire Air Pressure - too much or too little, for the
load.
• Vehicle Hitch Height - if trailer is not level with
ground, axle camber is misaligned.
• Maintenance - wheel bearing lubrication and
adjustment. Follow axle manufacturer’s instructions.
• Brakes - uneven or misadjusted brakes cause
irregular brake activation.
Tighten the 5, 6, 8, and 10 lug hubs in sequence
according to the following diagrams.
