7.5.2
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 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 and load capacity. Size changes such as rim width, center
piece
location,
recommendations, may result in an unsafe condition regarding stability.
7.5.4
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 possible dangerous separation of wheel from the axle. Be
sure to use only the nuts matched to the cone angle of the wheel.
Tighten the lug nuts to the proper torque to prevent wheels from coming loose. Use a
torque wrench to tighten the fasteners. If you do not have a torque wrench, tighten the
fasteners with a lug wrench, then immediately have a service garage or dealer tighten
the lug nuts to the proper torque. Over-tightening will result in breaking the studs or
permanently deforming the mounting stud holes in the wheels. The proper procedure
for attaching wheels is as follows:
1. Start all nuts by hand to prevent cross threading. DO NOT use a lubricant on
threads or nuts.
