Question

can you guess why the wheel of car move smoother when inflated with air​

Answer 1

Answer:

Because car's wheel is working on the road and road has much frictoin

Answer 2

Answer:

Air has lower density, viscosity, has higher expansion coefficient and also exerts lower & much more uniform pressure on each and every surface of the tube. Moreover, it provides a medium for contraction and expansion to the tire regardless of the rubber or any other material (i.e.) Air contracts or expands easily. Thereby, it reduces the wear and tear caused by friction of rubber with the rim of wheel.
