5.6 WHEELS AND TIRES
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.
The wheel and tire assemblies must be installed with the
directional tread pattern “arrows” (6) facing in the
direction of forward travel.
5.6.1 Removing Wheel and Tire Assembly
from Machine
1. Park the machine on a firm, level surface, 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 washers in an alternating
pattern.
7. Remove the wheel and tire assembly from the
machine.
5.6.2 Installing Wheel and Tire Assembly
onto Machine
Note: The wheel and tire assemblies must be installed
with the directional tread pattern “arrows” facing in the
direction of forward travel.
1. Position wheel onto studs on wheel end of axle.
WARNING
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.
