General Notes Pertaining To Load and Inflation Data Above
  • Load Values given at 6 psi for 25 mph and 30 mph are for calculating dual and triple load values only.
  • All load values are for maximum indicated speeds at low torque.
  • 20 mph load values also apply for low-speed high-torque field work.
  • High-Speed Cyclic (HS Cyclic) load-pressure data applies to low-torque spreading or spraying at field operating speeds up to 20 mph. Additional bonus loads permitted for this type application assume a rapid decrease from full to empty, where max load at max speed (20 kph) does not occur more than 15% of any work day.
  • Cyclic load-pressure data applies to low-torque harvesting type applications at field operating speeds up to 6 mph. Additional bonus loads permitted for cyclic applications assume a gradual load increase with unloading in the field.
  • Load & Carry load-pressure data applies to low-torque transport operations at max speeds of 6 mph for a max distance of 650 yards before discharging load and returning empty.
  • All load-speed-pressure data is valid for ground slopes up to and including 20%. When operating on slopes greater than 20%, please contact Michelin.
  • For moldboard plowing with single drive tires in the furrow, a minimum inflation pressure of 10 psi is required.
