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.

Mounting Guidelines

• To keep tire rotation in right direction, move each rim to opposite side of machine, rather than turning around rim.
• Dished wheels can be reversed.
• Tighten all bolts to specifications.
