Changing Wheel Spacing and Tread Width

In special cases, front tires can be set to wide position; however, wide position cannot be used with a loader. Using wide position during loader operation reduces front axle life.

Rear tires can be mounted in one position only.

CAUTION: Avoid injury! Remove wheels safely.

• Use a safe lifting device and support machine securely on jackstands.
• Block front and rear of wheel not raised to prevent machine movement
• Wheel can be heavy or difficult to handle when removing.

Mounting Guidelines

• To keep tire rotation in right direction, move each rim to opposite side of machine, rather than turning rim around.
• Dished wheels can be reversed.
• Tighten all bolts to specifications.
• Wide position—Install wheel with valve stem to the inside.
• Narrow position—Install wheel with valve stem to the outside.

Rear Wheel Positions

For eight position wheels, the mounting flanges on the rear rims are closer to one edge of the rim than the other, allowing the inner wheels to be mounted in different positions. By changing this position of the wheel on the rim, up to eight different tread widths can be achieved on some machines.

Various positions cannot be used because the tires would strike the fenders. Certain other positions may result in equal tread widths.

Tread width is measured from centerline-to-centerline of each tire.
