Rear Wheel, Tire, and Tread Guidelines

RXA0056701-UN-29AUG01

A - Clearance Between Inner Wheel and Fender

B - Distance between inside wall of Drive Wheel

C - Minimum Spacing between Duals

Reverse wheels on axles to provide a wider range of settings by changing rim position. Maintain correct direction of tire rotation by moving each wheel to opposite side of tractor.

IMPORTANT: Tires must have at least 25 mm (1 in.) clearance with fenders (A). Distance between tires (B) must be at least 1015 mm (40 in.) with tires equal distances from tractor centerline.

With sway blocks in upper position (sway allowed), minimum distance between tires must be 1090 mm (43 in.) to prevent interference.

Check for adequate clearance between implement and rear tires.

DO NOT mix radial and bias-ply tires on same axle.

Radial-ply tires do not require special rims.

Drive and dual tires mounted on the same axle should all be inflated to the same pressure.

Cast wheels are used inside and steel wheels on the outside on tractors with duals.

Over inflating a radial tire reduces machine performance. Using the correct inflation pressures will result in optimum tractive performance.

CAUTION: Avoid personal injury and tractor instability. Never operate with single tires having tread width less than 1520 mm (60 in.). Turning while operating at transport speeds with narrow tread widths can cause tractor instability. Increase tread width to improve stability.

IMPORTANT: Do not exceed 2800 mm (110 in.) between single tires for pulling heavy loads.
