Why do trucks have two tires at the back?

The trucks have double tyres at the back in order to maintain the heavy load of the truck. The large part of the weight of the truck is on the rear axle. Also, the double tyres help to increase the cross-section area which decreases the pressure. It helps in providing a better hold on the ground.

Why do trucks have wider back wheels?

You may also notice that some enthusiasts instead choose a much wider tire for the rear axles as compared to what they put up front.

Why do trucks and buses have wider tyres?

Answer: The trucks and buses have wider tyres with respect to the property that ” more the area, less the pressure”. As the area is more the pressure will decrease, so there will be less need for applying more pressure to handle the vehicle. The vehicle will move smoothly.

Why do buses and trucks have wider wheels?

Why the trucks and buses have broader wheels than the wheels of scooters or cycles? The trucks and buses are heavy and need to exert less pressure. Scooters and cycles have less wide wheels because they need more pressure for gripping.

Why do some trucks have double back wheels on them?

The double back wheels or “dualies” are intended for trucks that will be used for regular towing of heavier trailers. The dual wheels help distribute the weight of a heavier trailer. Without that added weight distribution, some trailers would be too heavy for single wheels and could cause the rear tires to blowout.

What is a dually rear wheel?

The technical term is “dual rear wheel”, called dually or DRW for short, and it all comes down to increase safety and stability when towing. With two wheels instead of one, a truck can distribute the weight of a payload more evenly and have improved stability when towing loads like horse trailers or large campers.
