TIRES/WHEELS/SPACING/BALLAST_______________________________________
TIRE AND RIM EQUIPMENT 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 end 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 the 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 satisfy 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 sidehill 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.
