Banking of roads at curve is necessary so as to avoid

What is banking of roads? Why it is necessary ?

Assertion : Improper banking of roads causes wear and tear of tyres. Reason : The necessary centripetal force is provided by the force of friction between the tyres and the road.

A : Banking of roads reduces the wear and tear of the tyres of automobiles. R : By banking of the roads one component of the normal reaction on the automobile contributes to necessary centripetal force.

Roads are banked on curves so that

Banking of road helps to increase the centripetal force and thereby increases the limit of maximum speed of vehicle with it can take the curve. Give the expression for the maximum allowed speed of a vehicle on a banked road with friction.
