I've digested this whole thread from the beginning and the Michelin PS 4S are now on my short list. I have to lose these stock P-Zero's before something bad happens. Initially the 555r and MT ET street were my first pick with the Firestone Indy 500's also being considered. The Michelins might be the best all around tire. It does give up a little straight line traction to a DR but is much better in wet and cooler conditions. I'm in Ky so we get a little of everything temperature and weather wise. I'm a new Hellcat owner but have been racing for many years. My first thought was to put the MT on and have the best tire from a dig (IMO) but I find myself driving mostly leisurely but with a couple of 0 to 60's thrown in everytime I get behind the wheel. The roads are curvy and hilly where I'm at. The fact is I would feel better with the M's over a DR in cooler or inclement weather. My Hellcat is not a daily driver and doesn't leave the garage in bad weather so I still may wind up with a DR to satisfy the Drag Racer in me but the PS 4S is very impressive.
