Tire Damage
For polyurethane foam filled tires, Dingli recommends that when any of the following are
discovered, measures must be taken to remove the machine from service immediately and
arrangements must be made for replacement of the tire or tire assembly.

A smooth, even cut through the cord plies which exceeds 3 inches (7.5 cm) in total
length.

Any tears or rips (ragged edges) in the cord plies which exceeds 1 inch (2.5 cm) in any
direction.

Any punctures which exceed 1 inch in diameter.

any damage to the bead area cords of the tire
If a tire is damaged but is within the above noted criteria, the tire must be inspected on a daily
basis to insure the damage has not propagated beyond the allowable criteria.
Tire Replacement
Dingli recommends a replacement tire be the same size, ply and brand as originally installed
on the machine. Please refer to the Parts Manual for the part number of the approved tires for
a particular machine model. If not using an approved replacement tire, we recommend 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), Unless specifically approved by the manufacture. 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.
Due to size variations between tire brands, both tires on the same axle should be the
same.
Wheel 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 mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT TORQUE
TO PREVENT LOOSE WHEELS, BROKEN STUDS, POSSIBLE
DANGEROUS SEPARATION OF WHEEL FROM THE AXLE. TO USE
