WebVehicle speed: Another important factor is your hydroplaning speed. The higher your speed, the more likely for hydroplaning to occur. Typically, your tires will start skidding at a hydroplane speed of 45-59 mph. Tires: Worn or bald tires can lead to hydroplaning. An underinflated tire can also be a cause for hydroplaning on wet surfaces. Web11 mrt. 2024 · - 1 - Formulas / ATPL theory summary (Rob Groothuis) Index ATPL.
