WebDynamic hydroplaning. A condition that exists when landing on a surface with standing water deeper than the tread depth of the tires. When the brakes are applied, there is a … WebThe moment at which dynamic hydroplaning occurs is a function of water depth, tire tread depth, tire pressure, and speed. For hydroplaning to occur, the depth of water on the runway must exceed the depth of the tire’s tread. The grooves that make up the tread on a tire are designed to disperse water out from underneath the tire.

Additionally, because a great number of … WebDynamic hydroplaning usually occurs at speeds above 45 mph. Viscous Hydroplaning only occurs on wet pavements with little or micro-texture. The typical example is a pavement with flushing (bleeding asphalt that completely covers the surface). Viscous hydroplaning can also occur on pavements that have been polished smooth by traffic.

WebMay 31, 2024 · By definition, hydroplaning is when a vehicle starts sliding uncontrollably due to the tires encountering more water than the treads can displace. When driving at high speeds over wet pavement, the water begins to push the front tires off the ground slightly, creating a thin film between the tire and the road.
