Although I drive a Civic Si, my driving habits are conservative. These tires corner well, have excellent braking characteristics in wet and dry, are quiet and well-behaved on the interstate, and look great. I've only had these tires on the vehicle for a couple of months, so I cannot comment on their capability in a New Hampshire winter. During the worst of the winter, however, I switch to dedicated snow tires, anyway. I can't think of anything I've disliked about these tires, other than one seems to be losing pressure at the rate of about 2 psi a week. I'll keep a close eye on it although a detailed examination of the tire off the vehicle revealed no obvious leaks or punctures.

I have only had these tires on a new car, a Hyundai Genesis, since Mar,2016. Their handling and stopping performance has been outstanding. Their road noise level is really annoying, which is probably a result of the performance design. The ride comfort is extremely poor, with every bump in the road transmitted to the passengers. The tire are Primacy X4M4 245x45x18 96V, which accounts for the noise and ride issues we have. The trend by auto makers to ever larger wheels and low profiles for looks is the real problem. They should provide for different wheel sizes other than the set size for a trim package. You can go up but not down.

My Primacy's are used on a collector sports car, I was looking for a performance tire that also gave a smooth and comfortable ride, this isn't easy to find in a low profile performance tire. The Primacy's filled the bill, they give a smooth and comfortable as well as quiet ride along with excellant handling. The handling was put to the test a month after I bought the Primacy's, when a car turned in front of me on a 2 lane road when I was going about 55 mph and I had to put my car almost sideways to avoid hitting the other car. My tires were squealing but they held the road and enabled me to keep in control of my car and avoid the accident. I cannot comment on wear life because I have only had them a few months but I would definetly recomend these tires.

I bought my 2013 Cadillac ATS AWD in December of 2017 and a few months later the tires were nearly bald with less than 12k miles on them. However, I found out that I needed a new rear end on my vehicle and that was touted as the reason for the extreme wear on my tires. Ignorantly I had the same tires put back on at full cost and here I am with tires that need replaced again and every time I drive in the rain I am hydroplaning all over the place. It doesn’t even have to be much rain and I’m sliding all over the place. This is very disappointing and frustrating not to mention expensive. I do not recommend these tires.

I have just purchased 4 Primacy MXM4 tires for my 2004 Pontiac Grand Prix GTP this tire offers excellent performance in both wet and dry conditions and a very quiet comfortable ride this tire is exceptional in every way with NO compromises. Michelin has hit a home run with this tire and I hope they never change the recipe for its success.

After replacing stock 16" wheels with 17" on my Focus ST, I wanted a high performance summer tire. The first set I bought were noisy and tracked badly on road grooves. Based on reviews of the Primacy MXM4, and the price I decided to give them a try, even though they aren't described as high performance. After 9k miles I couldn't be happier. They track and corner extremely well. Most of all, they are QUIET. Living in Arizona, I don't have much occasion to drive in rain or snow, but they have performed well in limited driving in those conditions. Great tires!

I've been a Michelin user for over 30 years. This is the worst Michelin tire that I have ever had. My car is a small hybrid that is never driven like a sports car. I have 19000 miles on the tires and the dealer said that the tires needed to be replaced - no warranty at all.

Best all season tire I've ever owned. The Primacy MXM4 isn't perfect nor even best in class in any single category, but is a standout because it excels in all (disclaimer: I don't live in the snow belt and haven't driven them in snow). The tire provides a superb balance between ride comfort and control... taught and confidence inspiring while being comfortable. For a non-directional tread its hydroplaning resistance is excellent and for an all season its lateral wet grip is exceptional. Dry grip is excellent for a tire in this class. It's also the quietest tire I've ever owned. Good, even wear. Will continue to buy this or successor.

I BOUGHT A 2020 CAMRY XSE 2.5 IN SEPTEMBER OF 2020 BRAND NEW ,MICHELIN PRIMACY MXM4 92V 235/40 19 CAME ON VEHICLE,HAS ALWAYS BEEN SERVICED AND ROTATED BY DEALERA AT ABOUT 28,000 MILES I STARTED TO GET VIBRATION IN STEERING AND FLOOR BOARD AND THROUGH OUT THE VEHICLE ON THE HIGHWAY SPEEDS STARTS ABOUT 50-55 MPH AND UP CAR NOW HAS A LITTLE OVER 29,000, THE TIRE HAS A 55,000 MILE WARR HAD IT BALANCED AND ROTATED TWICE AND THE SAME PROBLEM,ONE MECHANIC SHOWED ME ALL TIRES ARE SLIGHTLY OUT OF ROUND AND THAT IS CAUSING THE VIBRATIONS, WENT TO DEALER TWICE TO REPORT BUT THEY DONT FEEL IT BECAUSE THEY HAVE NOT TAKEN IT ON THE HIGHWAY NEED TIRES CHANGED UNDER WARR THEY ARE DEFECTIVE I WILL BE GOING TO DEALER AGAIN TO REPORT AND TO CONTACT MICHELIN. HOPE THEY OWN UP TO THE DEFECTS

I bought these MXM4 tires for my Mercedes C230 Sport sedan. They replaced the Michelin AS Plus I had on before. What a different it made to my car. Especially, the road noises generated by the AS Plus tires are completely gone! The ride quality and comfort are much better and the car felt like new again. These tires look great on the car as well. I would buy these tires again!
