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 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.
• Approved for 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 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.
Wheel Installation
It is extremely important to apply and maintain proper wheel
mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER
TORQUE TO PREVENT LOOSE WHEELS, BROKEN STUDS, AND POSSI-
BLE DANGEROUS SEPARATION OF WHEEL FROM THE AXLE. BE SURE
TO USE ONLY THE NUTS MATCHED TO THE CONE ANGLE OF THE
WHEEL.
