The rear tractor tyre is bigger in size than the front tractor tyres due to several important reasons. These reasons are

• Rear tyres are transmitting engine power to the ground. Bigger tyres provide a bigger contact area, which improves grip on the ground and reduces slipping.

• Tractor weight is mostly handled by the rear tyres, so these bigger tyres help distribute the load evenly and maintain stability.

• Rear tractor tyres produce more torque, which means they increase the ability of the tractor to pull heavy implements and loads efficiently.

• With heavy implements and loads at the back side, larger tyres help maintain balance and prevent the tractor from losing control.

• Front tyres are smaller because their main role is steering. Smaller tyres allow easier and sharper turning.
