I don't mind it, when my tires spin a little, while taking off from a stop sign.
Since I don't pull boat trailers up wet ramps these days, no problemo..
But when I'm doing 60mph, while there's standing water on the roadway,
and I hear my engine race, and see my RPMs speed up.. While my speed is actually decreasing..
That worries me a lot.. Because I know my steering wheel isn't going to work real well,
until my front tires get back down on the pavement.
The other reason I like higher tire pressure, is the handling is better.
However, I don't drive on bumpy roads very much..
I'll bet the faster lap times on the 'wet-handling course' wasn't all about hydroplaning.
They also had to make a few turns on Track 3.. AKA
handling..
