I agree with a previous reviewer. These tires made a huge difference on my car years ago. But I just put the Primacy on my SUV and I getting lower gas mileage. Where I drive and how I drive hasn't changed. Only the tires. I enjoy the comfort of these tires but the price wasn't worth lower mileage.

I have had the Primacy tires on my cadillas CTS for about a month now and I absolutely LOVE them. I feel like I have a brand new car. I debated on whether or not to stay with the Original Equipment Pilot tire and decided to try the Primacy and I am very pleased. Super smooth ride, great handling and better gas mileage so far for me. I liked the Pilot's and got 65000 miles out of them and so far I like the Primacy's better and sure hope to get a lot of miles out of them also.

I've had Michelin Primacy mxm4 for about a week now and I am overall very satisfied with performance of these tires: Pros: -Much faster accellaration (amazing). Definitely made a difference, the car accellarates much faster -Excellent Breaking, smooth stop no rolling or skidding -Sticks to the road, my old tires used to slide from a smallest bump now they simply ride over any obstacle Cons: -The only thing that did not improve much is the comfort of the ride, I still feel the bumps on the road...it's not as smooth as I'd hope it would be with brand new tires. I like luxury and the feeling of riding on air, which some people might not but that is what I was going for with these Michelin's. No comment: Don't know about fuel efficiency as of yet Did not ride in the rain, will update later

I have purchased this tire several times in my car owning history. I love the way my car manuvers and holds the road. They are a bit pricey but I know the tire and it is tried and true. I also like the fact that there is less road noise from this tire than others.

I first tried the Premier A/S 215/50 R/17 on a Ford Focus. This is a great tire but I did not have the handling and control I was used to. They are little softer and was getting some roll over. I want to thank Michelin for there great customer service satisfaction. With there 30 day satisfaction I was able to exchange the tires for the Primacy MXM4 215/50 R/17's and what a difference. The handling is great now. They are a little firmer than the Premier's but they are still smooth and quit. The handling is great and they are sure footed. They brought my Focus back to feeling like a sports car.

I have 2016 c300 Mercedes, I live in suburban and only drove 21k and went for annual inspections , the report came back as was “ I need two new tires in the rear , there is severe inside wear. Use extreme caution in ALL conditions.” Replaced now. I think there must be a defect in this models . This is ridiculous, I hardly drive this car.

I drive mostly highway miles. I accomplish routine maintenance as scheduled. I still have a little tread wear remaining, but am replacing my current set of MXM4 tires with the same --- my current set has over 80K miles on them. Vehicle: 2006 Honda Accord EX V6 4 dr. (287K miles +) These tires provide the performance and handling to instill confidence on most road conditions experienced in South-Central PA. I highly recommend them!

They came with the Lexus and that was part of the overall buying decision as we've preferred this brand for decades.These were always a bit noisier than what we've been used to, but just after hitting 32,000 it felt like we were riding in a tank. The road noise is unbelievably loud and the handling has gone to pot. I expected to get 45-55k from these tires. Has Michelin quality dropped? Looks like we'll have to research other brands as our trust in Michelin quality and longevity has seveerly faded.

Awd. Hemi. Rotated on tire consistently but with 20k on them, they are at 4/32nds and now handle rain and snow like garbage! My review ratings are from when they were new. They are terrible now when the roads aren't dry. Had to bite the bullet and buy four new tires- losing my pro-rate money because I can't keep the car on the road in bad weather! I was driving on a slushy turnpike and at every corner while driving less than 50mph, I would consistently lose my steering and start to plow straight in turns! I was approaching a red light recently on a flat, snow covered road and while driving less than 30mph, with substantial stop distance I couldn't get the car stopped. I ended up 5' into cross traffic by the time I could get the car stopped. This was standard powdered snow. Honestly, the dry cornering since new is basically just satisfactory. I was never impressed when trying to push my car a little in dry turns. I will never buy them again unless I suddenly live in a dry climate. Pennsylvania isn't that.

I bought these tires after using various brands over the years. I must say that they perform better than any tire that I've tried in the past. I drive a 9 year old lexus ls 430 and have had several set of tires on this car and these are the quietest yet most responsive tires of all. I'm really impressed.
