Question

Explain why the tyres of heavy vehicles are broad

Answer 1

the tyres of heavy vehicles are broad because the area of broad tyres is more and if the area is more then the pressure on the tyres is less. Therefore, the broad tyres reduces the pressure & heavy vehicles moved easily.

Answer 2

tyres of heavy vehicles are broad because area is increased and the pressure is decreased. the pressure exerted by the truck is spread over a larger area and thus there are lesser chances of skidding and slipping
