A study of the wet weather characteristics of five different pavements and ten different tires is presented. The pavements studied were a portland cement concrete, a seal coat surface treatment, a hot mix asphalt, a jennite surface and a longitudinally grooved portland cement concrete. The tires studied were several bias ply tires with different tread depths, a wide tire with full tread, a test standard tire, a smooth fiberglass belted tire and a full tread steel belted radial. In this study, wheel spin-down was used as the criterion for the detection of hydroplaning and the variables considered were tire tread depth, tire inflation pressure, water depth and wheel load. A sloping trough 800 ft. long, 30 in. wide and 4 in. deep was used in obtaining the data.
