Tire Inflation Specifications

For normal tractor operation use the inflation pressure shown in the tire and wheel chart. The inflation pressure are based on cold inflation pressure recommendations by Tire and Rim Association Inc.

For maximum tractor performance always adjust the tire pressure, within the minimum/maximum range to conform with the actual load on the tires. Under normal conditions use the minimum pressure rating for general drawbar work. Use the higher pressure rating, up to the maximum, for heavy three point hitch mounted equipment, or heavy front and mounted equipment.

Example A shows the cross section of a tire inflated for maximum load but with a minimum load on the tire. The tire tread is not making full contact with the ground which will give poor performance.

Example B shows the cross section of a tire with inflated pressure correctly adjusted to the load on the tire. The tire tread is making full contact with the ground which will give maximum performance.

Tire pressure can also be adjusted as required to safely meet the following requirements.

A.Severe Service. Tire pressure can be increased 28 kPa (4 PSI) more than the maximum pressure shown in the chart, for tires used in severe service. Severe service includes the furrow tire in regular plowing operations, the downhill tire in plowing and in other hillside operations.

B.Tires With Liquid Ballast. Inflate the tires 14 kPa (2 PSI) more than the recommended pressure. This will compensate for aeration that occurs when the tires are in motion.

IMPORTANT: During transportation on a railroad car or trailer, the tractor tires are often inflated to higher than normal operating pressures. Before using yourLowertractoror blockcheckelevatedthe airimplementspressure inandtheothertiresattachmto makentssurebeforethat
