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 stabil-
ity 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., with-
out 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 partic-
ular machine model.
If any of the following is discovered during tire inspection,
measures must be taken to remove the JLG product from ser-
vice immediately. Arrangements must be made for replace-
ment 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 fol-
lowing:
100 x 323 Tire – 311mm (12.25 in.) minimum
127 x 406 Tire – 394mm (15.50 in.) 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:
76 mm (3.0 in.) long
19 mm (0.75 in.) wide
19 mm (0.75 in.) 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).
