Traction: The larger surface area of the rear tires provides increased traction, which is essential for pulling heavy loads and working through challenging terrains. The wider tires distribute the tractor's weight over a larger area, reducing compaction of the soil.
Stability: The increased width and size of the rear tires enhance the tractor's stability, preventing it from tipping over when lifting or pulling heavy implements or attachments.
Weight transfer: When the tractor pulls or lifts a load, the weight of the tractor shifts towards the rear. The larger rear tires help to accommodate this weight transfer by providing additional support and preventing the tractor from becoming unbalanced.
Flotation: In certain agricultural applications, such as wet or soft soil conditions, large rear tires are used for flotation. They spread the tractor's weight over a broader surface, reducing ground pressure and preventing the tractor from sinking into the soil.
Load-bearing capacity: Larger rear tires have a higher load-bearing capacity, enabling them to support the weight of heavy implements and attachments without compromising the tractor's performance or stability.
It's important to note that the specific size and dimensions of rear tractor tires can vary depending on the tractor's intended use, power, and application requirements.
