Question

Th tires of a bus or a car are larger in size than the car. Why

Answer 1

The tyres of a bus or a truck have larger width than those of a car as truck and buses are big and used for heavy transport.
Their great weight need to be be spread over a large area. they use larger wheels as they carry large tonnes of weight,the large area reduces pressure on it so it has large tyre so that it culdnot shrunk.damage on roads .
Pressure=Force/Area
If the tyres would be small , the weight would puncture/damage the tyres as the tyres would not be able to bear the heavy weight of the truck..
