Solution
Banking of Roads:
The raising of the outer edge of a curved road above the inner edge to provide the necessary centripetal force to the vehicles so that they take a safe turn is called banking of roads.
Due to the high friction between the road and the tires, the tires wear out or tear down.
When the outer edge of a curved road is raised, the horizontal component of normal reaction provides a centripetal force, that results in less friction than in a flat road.
Therefore, the wear and tear of tires reduce due to the banking of roads.
