6.7 TIRES & WHEELS
Tire Wear and Damage
Inspect tires periodically for wear or damage. Tires with worn
edges or distorted profiles require replacement. Tires with sig-
nificant damage in the tread area or side wall, require immediate
evaluation before replacing machine into service.
Wheel and Tire Replacement
Replacement wheels must have the same diameter and profile
as the original. Replacement tires must be the same size and
rating as the tire being replaced.
Use of genuine parts is recommended.
Wheel Installation
It is extremely important to apply and maintain proper mounting
torque.
WHEEL LUG NUTS MUST BE INSTALLED AND MAINTAINED AT THE
PROPER TORQUE TO PREVENT LOOSE WHEELS, BROKEN LUG NUTS,
AND POSSIBLE SEPARATION OF WHEEL FROM THE AXLE. BE SURE TO
USE ONLY THE LUG NUTS THAT MATCH TO THE CONE ANGLE OF THE
WHEEL.
Tighten the lug nuts to the proper torque to prevent wheels from
coming loose. Use a torque wrench to tighten the fasteners.
Over-tightening will result in breaking the lug nuts or perma-
nently deforming the mounting holes in the wheels. The proper
procedure for attaching wheels is as follow:
1. Start all lug nuts by hand to prevent cross threading. DO
NOT use a lubricant on threads or nuts.
2. Tighten lug nuts in the following sequence.
