WebJan 31, 2013 · 9 x square root of tire Pressure for typical (dynamic) hydroplaning. I'm not aware of a published formula for reverted rubber (steam) hydroplaning or viscous (thin film) hydroplaning. Disclaimer: it's been a while since I went through the Gleim or Jeppesen books on this stuff so someone (preferably another flyer or CFI) check me but this is ... WebDynamic hydroplaning Effectively water-skiing, is basically impossible on a bike. The formula used in Aviation is 8.6 * √Tyre pressure (psi) = speed (knots) Assuming 40 psi that's 54.39 knots. That's 100 km/h 2. Reverted rubber hydroplaning The wheel skids, and that friction melts the rubber, which heats the water to steam, which lifts the wheel.
