Explanation:
Detailed explanation-1: -Wheels reduce friction by reducing the amount of sliding by converting it to rolling.
Detailed explanation-2: -To increase friction between the tyres and road, tyres are treaded that is oblique inscisions are made to increase the surface area thus making it rough. This way a greater rate of friction is achieved.
