TIRES AND WHEELS

6.9.1 Tire Wear and Damage
The tire and rim assemblies installed on machines have been approved by the tire
manufacturer for applications in which those products are intended to be used. The tire
and rims installed on each product model have been designed for stability
requirements, which consist of track width, tire compound, and load capacity. Tire
changes such as rim width, centerpiece location, larger or smaller diameter, tire
compound, etc., without written manufacturers approval, could result in an unsafe
condition regarding stability.
The tires and rims installed on machines are to be inspected daily as part of the daily
walk-around inspection. JLG requires that the daily walk-around inspection be
performed at each operator change during a shift and at each shift change.
6.9.2 Wheel and Tire Replacement
JLG recommends that any replacement tire be the same size and brand as originally
installed on the machine or offered by JLG as an approved replacement. Please refer to
the JLG Parts Manual for the part number of the approved tires for a particular machine
model.
If any of the following is discovered during tire inspection, measures must be taken to
remove the JLG product from service immediately. Arrangements must be made for
replacement of the tire(s) or tire assembly(s). Both tires/wheels on the same axle must
be replaced:
• If the overall diameter of the tire is less than one of the following: 100 x 323 Tire –
12.25 in. (311mm) minimum
• If any uneven wear is discovered.
A tire with significant damage in the tread area or sidewall requires immediate
evaluation before placing the machine into service. If a cut, tear, chunk, or other
discrepancy exceeds any one or more of the following dimensions, the tire must be
replaced:
3.0 in. (76 mm) long
0.75 in. (19 mm) wide
0.75 in. (19 mm) deep
• If the metal wheel is visible at any point through the tread area of the tire.
• If more than one discrepancy exists in any quadrant of the wheel (within 90 degrees
of one another).
6.9.3 Wheel Installation
It is extremely important to apply and maintain proper wheel mounting torque.
