WHEELS AND TIRES
JLG recommends 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 a JLG approved replacement tire, JLG
recommends 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).
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 tires are filled with air only when the machine leaves
the factory. JLG does not recommend the use of hydrofill
as a tire-fill substance because of possible environmental
impact.
Large-bore valve stems are used to help expedite tire
inflation and deflation. An inner tube may be used if a tire
does not provide an airtight seal. Check tire inflation
pressures when the tires are cold. When mounting a tire
on the wheel, the tire must be mounted on the wheel
respective of the directional tread pattern of the tire; this
produces a left or right tire and wheel assembly.
The wheel and tire assemblies must be installed with the
directional tread pattern “arrows” (
4
) facing in the
direction of forward travel.

Removing Wheel and Tire Assembly
from Machine
1. Park the machine on a firm, level surface, level the
machine, fully retract the boom, lower the boom,
place the transmission control lever in
(N) NEUTRAL, engage the park brake and shut the
engine OFF.
2. Place a Do Not Operate Tag on both the ignition key
switch and steering wheel, stating that the machine
should not be operated.
3. Loosen, but
DO NOT
remove the lug nuts on the
wheel and tire assembly to be removed.
4. Place a suitable jack under the axle pad closest to
the wheel being removed. Raise the machine and
position a suitable support beneath the axle. Allow
sufficient room to lower the machine onto the
support and to remove the wheel and tire assembly.
5. Lower the machine onto the support.
6. Remove lug nuts and lug washers in an alternating
pattern.
7. Remove the wheel and tire assembly from the
machine.
WARNING:
Risk of death or
serious personal injury. Mismatched tire sizes,
ply ratings or mixing of tire types (radial tires
with bias-ply tires) may compromise machine
stability and may cause machine to tip over.
