Excellent tires!

I have been a Michelin tire fan forever. If I buy a car and does not come equipped with Michelin tires, I always put a set on after about 3 or 4 months! I usually buy the Pilot Sport for handling but because my new car has 21 inch wheels, I chose the Primacy Tour A/S. They are just as great regarding handling and what a smooth quiet ride! You guys are awesome! I don't feel safe on any other tire!!

Smooth and quiet ride

Michelin came stock on our Cadillac and I really couldnt see putting any other tire on the vehicle. Cadillac and Michelin good hand in hand for smooth, quiet ride and these tires did not disappoint. Will always recommend Michelin to customers, friends and family.

Very happy with the Primacy

Bought the 18" Primacy to replace original tires on our Lexus RX350. I specifically selected 18" tires for this car because I want a smooth, cushioned ride. If you want low profile tires, buy a sports car and expect to replace them every 25k. The Primacy is quiet with a great ride. It performs well in all conditions especially on the interstate. We are at about 30k miles and they look great. Just had them rotated. Really happy with them.
