I would say any size of tires hydroplanes....nothing can beat nature that even your lawnmower will hydroplane. It's all about your speed and your personality on the road. One time when it was raining hard, I saw a Mustang SVT zoomed fast from my Ford Expedition ( uses 4 wheel drive when it 's raining hard...my only chance to use it in Texas :-) ) running around 80mph...in less than a minute, I passed a 3 car wreck....and the worst car damaged was the Mustang SVT!

My Crossfire hasn't seen rain nor snow! It's safety tucked in bed...in the garage

Drive safely when it's raining, snowing or flooding.
