5.23 Model 8042, 10042, 10054 Legacy Rev. 10/03
Axles, Drive Shafts, Wheels and Tires
5.5 WHEELS AND TIRES
The Model 8042 uses a wheel type with nominal
dimensions of 9" x 24". An optional wheel type with a
nominal dimension of 13" x 25" is available.
The Model 10042 and 10054 uses wheels with nominal
dimensions of 13" x 25".
The specified size and ply rating (star rating for radial tires)
for this vehicle is 13.00-24, 12-ply or optional 15.5 x 25
Radial, directional tread (8042), or 17.5 x 25 Radial,
directional tread (10042/10054). Make sure the
replacement tire is of the same size and ply rating (star
rating for radial tires) as all of the other tires. A higher ply
rating (star rating for radial tires) can be used, but only
when all four tires have the same ply rating.
In standard configuration, the tires are filled with air only
when the vehicle leaves the factory. There is a foam fill
option available if the use of a tire-filling substance is
desired. Having tires filled has a positive effect on the
weight, stability and handling characteristics of the vehicle,
especially under load. 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” (8 and 9) facing in the
direction of forward travel.
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 vehicle
stability and may cause vehicle to tip over.
