Answer 2

The wheels of buses are not only heavier than car ones but also Broader than that of car , Because the bus has to carry heavy loads as compared to cars and Bus have broad and heavy wheels to reduce pressure on the ground , As you must be knowing Pressure = Force/Area , So we can see that Pressure is inversely proportional to the Area , greater the area , lesser the Pressure. In case of car , it doesn't has to carry heavy loads so wheels of cars are smaller as compared to Buses.
