5.6 WHEELS AND TIRES
It is recommended that a replacement tire to be the
same siz e, ply and brand as originally installed . Refer to
the appropriate parts manual for ordering information. If
not using an approved replacement tire, the replacement
tires must 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.
• Approv ed for the application by the tire m anufacturer
(including inflation pressure and maximum tire load).
Unless specifically approved by JLG, do not replace a
foam filled or ballast filled tire assembly with a pneumatic
tire. Due to size variations between tire brands, when
selecting and installing a replacement tire ensure both
tires on the axle are the same.
The rims installed 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
unsafe condition regarding stability.
The wheel and tire assemblies must be installed with the
directional tread pattern “arrows” (6) facing in the
direction of forward travel.
