9. TIRES
WARNING
• Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper
equipment.
• Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure show in
the operator's manual.
IMPORTANT
• Do not use tires other than those approved by KUBOTA.
• Dual tires are not approved.
NOTE
• When optional different-diameter tires are fitted on the machine, the travel speed display mode must be
changed. Otherwise the travel speed will not get correctly displayed. Such mode switching is also needed
when the original tires are back on the machine. (See page 9-S22.)

Through the tire pressure is factory-set to the prescribed level,
it naturally drops slowly in the course of time. Thus, check it every
day and inflate as necessary.
 Recommended Inflation Pressure
• Maintain the pressure shown below for normal use.
NOTE
• Maintain the maximum pressure in front tires, if using a
front loader of when equipped with lots of front weight.
