I previously had a set of Yokohama P215/50VR-17 AVID V4S high performance all-season tires. Those tires had excessive road noise and did not offer the best ride comfort. I recently got a flat tire and decided that it was time to get new tires since the Yokohama's were only a couple thousand miles away from the end of their tread wear life anyway. I decided to go with the Michelin 215/50R-17 Primacy MXV4 XL tires based on the reviews and great ratings. I wanted grand touring tires instead of high performance ones like my previous tires. I've only been driving on these new Michelins for about 500 miles (break-in period) and I can definitely tell a huge difference! The road noise is considerably less than my previous tires and they ride so much more smooth. No longer do I have to blast my radio at high speeds to overcome the road noise. They also absorb bumps and dips in the road a lot better than the tires I had before. Responsiveness is quick and accurate. I'm really glad that I spent a little extra cash on some quality and great performing tires.
