the vehicles equipped with propulsion engines, it is recommended to use wide tires with thick strips to prevent slippage, the warming and have good control off the brake
Because of carrying heavy load
Answer: Large tyres provide larger surface area touching the ground, thus providing the more pulling power. Basically tractors have larger rear tyres because tractors dont have to operate at higher speeds, thus getting the same ground speed with larger tyres. Moreover gear ratios dont have to be as high as because of the tyres.Tractors have big rear tires because the larger the surface area of the tractor's wheels touching the ground, the more pulling power you have. Like how tractor pulling have large tires.
Another reason is that the tractor doesn't have to operate at a higher speed to get the same ground speed with larger tires. Gear ratios dont have to be as high because of the large tires.
