6.4 TIRES & WHEELS
Tire Inflation
The air pressure for pneumatic tires must be equal to the air
pressure that is stenciled on the side of the JLG product or
rim decal for safe and proper operational characteristics.
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
assembly.
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 inches (7.5 cm) in total length
• any tears or rips (ragged edges) in the cord plies
which exceeds 1 inch (2.5 cm) in any direction
• any punctures which exceed 1 inch 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. Please refer
to the JLG Parts Manual for the part number of the approved
tires for a particular machine 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
• Approved for the application by the tire manufacturer
(including inflation pressure and maximum tire load)
Unless specifically approved by JLG Industries Inc. do not
replace a foam filled or ballast filled tire assembly with a
pneumatic tire. When selecting and installing a replacement
tire, ensure that all tires are inflated to the pressure recom-
mended by JLG. Due to size variations between tire brands,
both tires on the same axle should be the same.
