5.10 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 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
original
• Approved for 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.
5.10.1 Removing Wheel and Tire Assembly from
Machine
1. Park machine on a firm, level surface, level machine, fully
retract boom, lower boom, place transmission in (N)
NEUTRAL, engage parking brake, and shut engine OFF.
2. Place a Do Not Operate Tag on both ignition key switch
and steering wheel.
3. Loosen but DO NOT remove the lug nuts on the wheel
and tire assembly to be removed.
4. Place a suitable jack under axle pad closest to wheel
being removed. Raise machine and position a suitable
support beneath axle. Allow sufficient room to lower
machine onto support and to remove wheel and tire
assembly.
5. Lower machine onto support.
6. Remove lug nuts and washers in alternating pattern.
7. Remove wheel and tire assembly from machine.
5.10.2 Installing Wheel and Tire Assembly onto
Machine
Note: The wheel and tire assemblies must be installed with
directional tread pattern “arrows” facing in direction of forward
travel.
Note: Verify valve stems face outward on all wheel and tire
assemblies.
1. Position wheel onto studs on wheel end of axle.
2. Install wheel washers onto studs.
3. Start all lug nuts by hand to prevent cross threading.
Apply one drop of lubrication oil.
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.
