Rear Wheel, Tire, and Tread Guidelines

RXA0056701-UN-29AUG01

A - Clearance between inner wheel and fender

B - Distance between inside walls of drive wheels

C - Minimum spacing between duals

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: Tires must have at least 25 mm (1 in.) clearance with fenders (A). Distance between tires 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.

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

Check for adequate clearance between implement and rear tires.

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

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

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

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