An airplane tire will hydroplane at a speed in knots equal to nine times the square root of the tire pressure in PSI. The real trick is undoing the little cap on the tire valve and reading the tire gauge while turning left base.

Not an airplane fact, but when I took classes for driving ambulances (CEVO), they always cited 35mph as the speed where an ambulance can hydroplane on some amount of water that I cannot recall. Something with surface tension. Iâm not a scientist.

In aviation circles they always called it âstanding waterâ here meaning âthe surface is liquid not a wet solidâ Airplane tires also have very simple or no tread at all, so that isnât a factor. Thereâs also the fact that during the landing roll, the airplane is partially or even mostly supporting its weight on its wings still; so at any significant airspeed you donât have 100% of the shipâs weight on the wheels.
