5.7 TIRES AND WHEELS
Tire Wear and Damage
The tire and rim assemblies installed on RS 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 RS 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.
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
127 x 406 Tire – 15.50 in. (394mm) 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.

(within 90 degrees of one another).
