Tractors or construction vehicles have very large wheel diameter in the rear and front also. As these vehicles find their job in places where contact is not hard enough like loose sand, muddy etc and hence need to provide required (high in values) torque/ power/ rigidity without any skid. Very large diameter and deep grooves on the tyre provide traction for this purpose. Also as they are heavy in weight, load is being shared by it (in tractor 70% load is shared by rear wheel)
