The students may think that the larger area of the broad tyres used may undergo larger friction and wear and tear of the tyres may occur. But the main purpose of the broad tyres used in the heavy vehicles is to reduce the pressure and hence force on the surface of the tyres.
If the tyres of the heavy vehicles are kept board , then the force of a weight of the vehicle on the tyres get distributed over the surface of the tyres and the forces experienced by the tyre s become relatively less.
