Dictionary

Aquaplaning is a condition in which a film of water separates a tire and a road surface. It occurs when the pressure of the wedge of water, not pushed out of the area of contact of the tire with the road, raises the tire above the road. The tendency to aquaplaning depends on the thickness of the water film on the road surface, the speed of the car, the shape of the tread pattern, its wear and the pressure exerted by the tire on the road.
