Why heavy vehicles are provided with more tyres?
Heavy trucks have broad tyres because broad tyres have large area of contact and less pressure on the ground.
Which vehicle have more tyres?
The goods vehicles have a greater number of tires to reduce pressure on the road created due to contact with it.
Why do large trucks have so many tires?
The lift axle helps spread the weight of an especially heavy load. And by raising the axle when it’s not needed, the driver can save wear and tear on that set of tires. More and more trucks have the extra wheels because more and more states are requiring them.
Why tractors have broad tyres?
Pressure exerted by an object is inversely proportional to its surface area. So, tractors have broader tires so that the pressure exerted by them on soft soil (typical for farmlands) is comparatively less and they do not sink in as they are very heavy indeed.
Why trucks carrying heavy loads have many wheels?
Answer: Load carrying heavy vehicles have large number of wheels in order to reduce pressure on the contact patch on road. With large number of wheels, it becomes easy to distribute the entire pressure of loads in an even manner.
Why do the load carrying heavy vehicles have number of wheels?
So, the load-carrying heavy vehicles have a large number of wheels so that the pressure on the road is reduced due to the larger contact area. Also, using a large number of wheels ensures that the force due to the load is shared among the tyres and no single tyre is under stress.
Why do tractors have broad tyres?
Why are heavy trucks provided with double tyres 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.
