Great Handling Tire

I bought the Tires about 5 months ago and out of all the tires I have had on my 90 Corvette these are the best yet, Handling is great, Ride is very Good and they seem to be wearing very well.

The grip !!!!!

Had summer Nittos On my mustang in Houston Texas ,,, moving to NC so I needed some good all Season tires …. As Soon as I drove off with my new Michelins I loved them I could instantly tell the grip and handling was light years above my Nittos … love these tires !!! Thanks Michelin !

Costly But Worth It

The Michelins I got are actually the "Cross Climate", NOT the "Pilot Sport". They cost a fortune but I've decided they are worth it. In addition to being winter certified the handling, ride and road noise all significantly improved. Quite amazing. A lot like having a different and better car. You won't regret having these.
