Replaced my rear Super Sports and car seems a little squirrely in the front?

You have your old MPSS in the front too, yes? Mismatching brands can do this

Assuming you have 4 Michelin Pilot Super Sports on the car, it could be that when the dudes put the rears on they checked the pressures on all 4 tires before returning it to you. I find that tire dudes tend to put the factory spec air pressures every time, which is like, 37 front - 44 rear? - so if you were used to something like: 33 front and 38 rear, your front end will feel noticeably different (Squirrelly, Floaty, Slippy) for sure.

I typically run 33 or 34 in the front and 38 out back. Lately as the temps have been changing here I'm finding that I'm feeling more understeer -I checked my cold pressures this morning, and they were like 30 front and 35 rear, which is too low. I adjusted up to 36 front and 40 rear this morning to see how it feels, and after running that all day, (air temps between 65 & 95˚) with elevation changes from sea level to about 3000 feet - I definitely want to let a little out of the fronts. - point being, a couple pounds can really make a difference so maybe check that first.

Is this a statement or a question? If a question, how about info on what went on and what came off.

New tires tend to be squirmy because now you have very tall tire blocks. after a few heat cycles, they tend to stiffen up and handle better. give it a hundred miles or so.

Thanks Comanche after I posted this I thought the same and am checking pressure. And yes same tires on front just wore out rears guys.

Yeah they had my fronts @ 40 and rears at 48 psi. No wonder!

40 lbs up front would definitely make that front end squirrelly! glad you got it figured out.
