The researchers tested how well a tractor tire performed on different types of ground. They found that the tire did better on the second pass, with more traction and less resistance. This improvement was greater on rough ground. However, the differences between two-wheel and four-wheel drive tractors were not fully explained by this. It seems that four-wheel drive tractors are better at matching power, weight, and speed with the job they are doing.
