6.5 TIRES & WHEELS
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 replace-
ment tire, we recommend that replacement tires have the follow-
ing 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 pneu-
matic 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 and Tire Replacement
The rims installed on each product model have been designed
for stability requirements which consist of track width, tire pres-
sure, 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.
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
