Great tires!
This is my third set of Michelin PS4S tires on Porsche 911 and Boxster and love them! Great tires and worth every penny!
Rockin' the Creek road
My new skins replaced some old Goodyear Eagles from Germany and the improvement was dramatic. I live on a remote rural property and the creek road I travel is challenging, requiring grip, grip, grip. I'm totally satisfied so far, that said, I have less than 1k miles on the kit. I'll have a complete review at 5k.
Love them
Absolutely love these! So much fun! great traction and handling on tight curves at high speeds (70+) even in wet conditions. Significantly quieter than my all seasons. Very sad to have to switch them out because of New England temps. Another reason to look forward to spring!
