My 350Z on Kumho XS's in a lot of rain:

It felt like I was driving a shopping cart with those "spinny" wheels at all 4 corners. With water on course, the same input can give you wildly different results from one spot on the course to the next. Traction was "like a box of chocolates" and steering response was like a game of "Marco Polo".

I can't imagine any tire with tread on it being as bad as Kumho XS's in the wet, so I expect your RE11's won't be as bad
.
Wrong.

By increasing the tire pressures, you reduce the contact patch and help reduce hydroplaning. Had a rain event last year, one run at the normal pressures I run and the next with 4 psi more all around. The higher pressure was noticeably better.
