Problem Cause Remedy
• Do not weld, braze, otherwise repair, or use a damaged
rim.
• Never attempt tire repairs on a public road or highway.
• Use jack stands or other suitable blocking to support the
loader while repairing tires.
• Insure jack has adequate capacity to lift your loader.
• Insure jack is placed on a firm level surface.
Do not put any part of your body under the loader or
start the engine while the loader is on the jack.
• Torque lug nuts to specification after reinstalling wheel.
Check lug not torque daily until torque stabilizes.

10.00 x 16.5 40 - 45 PSI (276 - 310 kPa)
4. 10B Tire Rotation
The front and rear tires will wear at different rates. For
even wear move the front tires to the rear and the rear tires
to the front when wear is first noticed.
If two tires become worn more than the other two put the
two worn tires on the same side.
When new tires are installed, always keep tires the same
size on the same side of the loader. Two different size tires
on the same side of the loader will cause drive chain wear,
tire wear and a loss of power.
