FOUR WHEEL DRIVE TIRE COMBINATIONS
The tires fitted to tractors with optional four wheel drive have been carefully selected to match the gearing of the
transmission and axles. When replacing worn or damaged tires, always install tires of the same make, model
and size as those removed. The installation of other tire combinations may result in excessive tire wear, loss of
useable power or severe damage to driveline components. If in doubt, consult your authorized dealer.
Radial Tire Identification
Radial tires are identified according to rating by a star code - -
either one star (
), two stars (
) or three stars (
).
Tires with
are inflated to a maximum of 1.2 bar or 18 PSI.
Tires with
are inflated to a maximum of 1.6 bar or 24 PSI.
Tires with
are inflated to a maximum of 2.0 bar or 30 PSI.
Refer to the identification panel on the side of the tire sidewall.
TIRE PRESSURES AND PERMISSIBLE LOADS
IMPORTANT: The figures in the following charts are for guidance only. Tire specifications vary by tire
manufacturer. For exact tire loading information, refer to the information provided by the manufacturer of the tires
on the tractor.
To avoid the possibility of tire to rim creep, tire pressures below 0.40 bar (6 PSI) with radial tires and 0.80 bar
(12 PSI) with bias ply should not be used for operations having a high torque requirement, e.g., subsoiling,
plowing, heavy cultivation, etc.
Tire loading figures in the following tables are for a single wheel. To determine the maximum tire loading for single
wheel applications, multiply the load figure in the table by two, the total number of wheels on the axle.
Example:
Rear
2 wheels (singles) x table figure = Maximum tire load
To determine the maximum tire loading for units with duals, multiply the load figure in the table by the total number
of wheels on the axle, then multiply by 88%.
Example:
Rear
4 wheels (models with duals) x table figure x 88%= Maximum tire load
Axle loading must be within the capacities listed in Section 3 of this manual.
Remember the information in the charts and the examples cited are for guidance only. For exact information
regarding inflation pressures and tractor loading, consult your authorized dealer or the tire manufacturer.
When front mounted implements are fitted, front tire loads may be increased by up to 35% with no increase in
inflation pressure when operated at speeds not exceeding 20 KPH (12 MPH).
At speed not exceeding 8 KPH (5 MPH), the load on the front tires may be increased by 50% provided the inflation
pressures are increased by 25%.
When mounted implements are used, rear tire loads may be increased by up to 20% with no increase in inflation
pressure when operated at speeds not exceeding 20 KPH (12 MPH).
