C. Tire and Wheel Replacement
It is recommended that a replacement tire to be the same size, 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.
• Approved for the application by the tire manufacturer (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.
