One other benefit of MPSS over PZero (there are many) is elimination of acorns. I've been running exclusively Michelin Pilots (PS, PS2, PSS) on 911s for 15 years or so. So when my 991 exhibited strong acorning on every low-speed turn during its first winter I came on here and searched till I found it was "normal." Asked a few "why is that -- I've never had it before" questions and everyone who responded said essentially, "Modern tires, new suspension geometry on 991."

So when I wore my rears out at 7500 miles and naturally replaced all 4 (NOT a fan of the PZero) this summer, I didn't even think about acorns. Until about three weeks into our winter, when it dawned on me that I hadn't had a single instance of them. Including one morning in the low-twenties (unusual in Atlanta.)

Yup. Here in Kalifornia, there's actually a law about it. First thing I do when I pick up my car from service is lower the pressures. The first time I drove home with the pressures way high I thought I was gonna lose a filling.

I had MPSS on last car and loved them; going back once P-0's are done.

Op: Congrats on the GTS!
