| | A properly inflated radial is six to eight percent more efficient than a bias-ply tire. Radial tires need more management than bias-ply tires. Matching inflation pressures to loads is critical to optimizing the performance of radial tires.
- Don't exceed the maximum permissible operating weight/load for the tractor tires. Consult the owner's manual or tire manufacturer's guidebook for recommended pressures for given loads.
- Check tire pressures regularly.
- Use an accurate pressure gauge for measuring low pressures. An error of 2 psi (14kPa) won't have a big effect on performance with 30 psi (207 kPa) tire pressure, but with pressures of 12 psi (83 kPa) or less, 2 psi (14 kPa) is a 20% error.
- Never exceed 35 psi (241kPa) inflation pressure, as severe damage or personal injury can occur should the tire separate from the rim.
- The pressure recommendations molded into the side of tires are maximum pressures for maximum loads. Using these pressures at less than maximum load can adversely affect tire and tractor performance.
- Always inflate and ballast all tires on the same axle to the same level.
- Remember that changing tire size will change travel speed - a factor to consider when adjusting ballast to match travel speed.
