Our 2014 Chrysler 300S was equipped with Firestone Firehawk tires from the factory. The road noise was extremely agitating especially on cement roads or bridges. We had a constant noise which was diagnosed as wheel bearing noise but after replacement of the bearings the noise continued and it was suggested it might be caused by the tires. As a licensed aircraft mechanic with former auto shop experience I doubted that suggestion, however upon installation of the MXM4 tires the noise disappeared, the handling is totally more enjoyable, the ride is 100% improved and we are now enjoying what rides, drives and feels like a new car!

I had vibration problems with my 2016 Nissan Maxima. I finally installed the Primacy MXM4's and it has transformed the vehicle. These tires ride very quietly and very smoothly, and all the vibrations are gone. This should be standard equipment on the Maxima. If you are considering either the Primacy MXM4 or the Premier A/S, choose the MXM4. It is a quieter and smoother riding tire.than the Premier A/S, and handles and brakes extremely well.

We bought these tires in October 2015 and have had them rotated every 5000 miles. I took the car in for an oil change and tire rotation Monday and was called to the service center by the auto technician to look at the tires he gauged them at 3/32 with only 10114 miles on these tires. Do not buy these tires.

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

These came as original equipment on my 2014 Acura RDX -- they rode very well until about 6 months ago, but at 37k they started getting noisy and at 43k miles now they are almost down to the wear bars (all 4 ware worn evenly down to 3/32 of tread remaining per Acura dealer based on this week's service report). I'll drive carefully in the rain for the next couple of months, but at 45k will definitely change tires before the fall/winter weather hits. So expect 40-45k miles at most out of these, as I am very careful about rotating and other maintenance...

I have these tires on two automobiles, our Volvo and Buick. The Michelin tires provide a wonderful smooth and capable ride and provide driving confidence in all sorts of weather from dry pavement to Wisconsin snow storms. We are very pleased to have both cars equipped with these fine Michelin tires.

I bought these tires for my 2010 Focus with 17 in wheels so my version have a pretty small sidewall. So ride is important to me. These perform very well in the little bit of time I've owned them. (3 months/ 7000 miles) I drive 90% hi-way. Great at high speed in all conditions. Drove home from airport in a blizzard and I felt very in control. Great in wet and dry. Have yet to hear them make any noise in the corners. They suck up the bumps well too. Another thing I like is that the sidewall protrudes a bit more than most tires and protects the wheel lip very well. So if you do happen to bump a curb your wheel will be ok. I did have a small issue getting them balanced but I put that more on the place that balanced them, my wheels, and my pickiness at highway speeds. Great Tire. I don't mind spending a little more. I think all Michelin tires are worth the extra coin. Let's face it, this is all that keeps you on the road.

I have used two full sets of these tires on my 2013 Camry V6, and they provide great handling. The side walls are pretty stiff, and they have pretty good cornering traction. They don't last as long as stated on the warranty (at least for me) but they are a good balance of grip and treadwear. Way better than Sumitomo A/S PO2. I also love the low rolling resistance, because I do a lot of highway driving.

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.

These tires are worth the money. I've previously had Yokohama, which were so noisy I took them back for a set of Continental, which were quieter, and lasted 53K, but these Michelins are by far and above the quietest tires I have ever driven on. Wet traction, stopping, cornering - in all conditions they perform flawlessly. I live in AZ, so I don't drive in snow, so I can't comment on how they handle in the white stuff, nor do I care.
