Tire Damage
For pneumatic tires, JLG Industries, Inc. recommends that
when any cut, rip, or tear is discovered that exposes sidewall
or tread area cords in the tire, measures must be taken to
remove the JLG product from service immediately. Arrange-
ments must be made for replacement of the tire or tire assem-
bly.
For polyurethane foam filled tires, JLG Industries, Inc. recom-
mends that when any of the following are discovered, mea-
sures must be taken to remove the JLG product from service
immediately and arrangements must be made for replace-
ment of the tire or tire assembly.
• a smooth, even cut through the cord plies which
exceeds 3 in. (7.5 cm) in total length
• any tears or rips (ragged edges) in the cord plies which
exceeds 1 in. (2.5 cm) in any direction
• any punctures which exceed 1 in. (2.5 cm) in diameter
• any damage to the bead area cords of the tire
If a tire is damaged but is within the above noted criteria, the
tire must be inspected on a daily basis to insure the damage
has not propagated beyond the allowable criteria.
Tire Replacement
JLG recommends a replacement tire be the same size, ply and
brand as originally installed on the machine. lease refer to the
JLG Parts Manual for the part number of the approved tires for
a particular machine and model. If not using a JLG approved
replacement tire, we recommend that replacement tires have
the following characteristics:
• Equal or greater ply/load rating and size of original
• Tire tread contact width equal or greater than original
• Wheel diameter, width, and offset dimensions equal to
the original.
Unless specifically approved by JLG Industries Inc. do not
replace a foam filled tire assembly with a pneumatic tire.
When selecting and installing a replacement tire, ensure that
all tires are inflated to the pressure recommended by JLG. Due
to size variations between tire brands, both tires on the same
axle should be the same.
Wheel Replacement
The rims installed on each product model have been
designed for stability requirements which consist of track
width, tire pressure, and load capacity. Size changes such as
rim width, center piece location, larger or smaller diameter,
etc., without written factory recommendations, may result in
an unsafe condition regarding stability.
