5.6 WHEELS AND TIRES
It is recommended that a replacement tire to be same
size, ply and brand as originally installed. Refer to
appropriate parts manual for ordering information. If not
using an approved replacement tire, It is recommended
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.
Foam filled tires have a positive effect on the weight,
stability and handling characteristics of the machine,
especially under load. The use of hydrofill as a tire-fill
substance is not recommended 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.
5.6.1 Wheel and Tire Assembly Removal
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 an Do Not Operate Tag on both the ignition
key switch and steering wheel.
3. Loosen but DO NOT remove the lug nuts on the
wheel and tire assembly to be removed.
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.
