5.5 Tire and Wheel

Tire replacement
ZOOMLION recommends a replacement tire be the same size, ply and brand as originally installed on
the machine. Please refer to the ZOOMLION Parts Manual for the part number of the approved tires for
a particular machine model. If not using a ZOOMLION approved replacement tire, we recommend that
replacement tires have the following characteristics:
a) Equal or greater ply/load rating and size of original;
b) Tire tread contact width equal or greater than original;
c) Wheel diameter, width, and offset dimensions equal to the original;
d) Approved for the application by the tire manufacturer (including inflation pressure and maximum
tire load).
Unless specifically approved by ZOOMLION do not replace a foam filled or ballast filled tire assembly
with a pneumatic tire. When selecting and installing a replacement tire, ensure that all tires are inflated
to the pressure recommended by ZOOMLION. Due to size variations between tire brands, both tires on
the same axle should be the same.
Wheel and tire replacement
The rims installed on each product model 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 an unsafe
condition regarding stability.
Wheel installation
It is extremely important to apply and maintain proper wheel mounting torque.
Wheel nuts must be installed and maintained at the proper torque to prevent loosen wheels,
broken studs, and possible dangerous separation of wheel from the axle. Be sure to use only nuts
matched to the cone angle of the wheel.
Tighten the lug nuts to the proper torque to prevent wheels from coming loose. Use a torque wrench to
tighten the fasteners. If you do not have a torque wrench, tighten the fasteners with a lug nuts to the
proper torque. Over-tightening will result in breaking the studs or permanently deforming the mounting
stud holes in the wheels. The proper procedure for attaching wheels is as follows:
a) Start all nuts by hand to prevent cross threading. DO NOT use lubricant on threads or nuts;
b) Tighten nuts in the following sequence;
