* Steering and Turning: The front wheels are responsible for steering. This constant turning and maneuvering, especially on uneven terrain, causes significantly more friction and scrubbing action on the tire treads compared to the rear wheels which generally follow a straighter path. This scrubbing wears down the tread unevenly and rapidly.
* Braking (in some tractors): While most braking is done on the rear wheels, some tractors use front wheel brakes as well, contributing to increased wear.
* Higher Load during Turning: When turning, a significant portion of the tractor's weight shifts to the outside front wheel, increasing the load and pressure on that tire, leading to faster wear.
* More Exposure to Debris: The front wheels often encounter more debris, rocks, and other obstacles than the rear wheels, which can cause cuts, punctures, and increased wear.
* Less Traction (sometimes): Depending on the tractor and its use, the front wheels might not always have optimal traction. This can lead to more slippage and increased wear.
In summary, the combination of steering, turning forces, potential braking, uneven load distribution, and exposure to debris results in a higher rate of wear and tear on the front tires of a tractor compared to its rear tires.
