('96 850 Turbo) I was running a set of Michelin MXV4+ Energy tires and I thought they were really good at first, very exspensive V rated tires... but soon I learned they hydro-planed fairly easily, not "off the roadway into the woods" type thing, but the steering would get "greasy" at even 55mph on a wet road, much less faster.
Also when cornering they would whine at good speed (60mph) on a fairly tight corner. Never lost traction but the did get whiny and a little "greasy" feeling....not reassuring. You could call my driving style... spirtited.
Long story short, after I only got 31k miles (NO tread warranty) out of a $800 set of tires I did some research...

I got a set of BF Goodrich Traction T/A in the standard P205 55R 16 size for the car... My god what tires!
Wet weather they grip the road like a cat. On those same corners at 75mph no whine at all and I could feel the G-force in my guts. Like being on a rail. They are V rated also but cost $100 (US) dollars less and have a 60k tread life warranty!!! Just wanted to share!
Peace.
