How do variations in tire pressure affect the ground pressure and traction of a wheel loader, and what is the optimal pressure for soft ground?

Variations in tire pressure significantly affect the ground pressure and traction of a wheel loader. Ground pressure is the force exerted by the tire on the ground, measured in pounds per square inch (PSI). Traction is the friction between the tire and the ground, which allows the loader to move and exert force. Higher tire pressure results in a smaller contact area between the tire and the ground, increasing the ground pressure. This increased ground pressure can be beneficial on hard surfaces, as it reduces rolling resistance and improves fuel efficiency. However, on soft ground, high tire pressure can cause the tires to sink into the gro....
