These tires, MXM4 in 225/45/17 are on my everyday ride. They replaced a set of Pilot A/S Plus, which replaced Pilot's. I only run these 3 out of 4 seasons, using dedicated winter tires. For the 3 seasons I do run these they hold up very well. Certainly grippy enough for everyday driving with spirited moments. They actually grip better than the Pilot A/S Plus'. Hydroplaning resistance is also better. As for noise, these are very well designed and are actually rather quiet at all speeds. The only suggestion I would make to improve them is for a rim guard rib in the next generation.

In February after putting these tires on my EOS we drove up to South Lake Tahoe from Sacramento. The tires were great in the rain and in light snow on the way home; while on some windy roads. They grip great and are quiet on the road! I will definitely purchase these tires again!

I have the Primacy MXM-4's on an Acura RL and find them to be excellent in all kinds of weather (I live in NW Pennsylvania so we do get "all kinds of weather"!) I lived in Europe (Germany) for many years and almost always drove Michelin, often at very high speeds and again, in all kinds of weather. I'll be ready for new tires in about a month (these have 39,000 miles on them) and have looked at other brands (as I always do for some reason!) but am sure I'll stay with Michelin, most likely either the Primacy again or the Pilot. It's also a "confidence in the brand" thing for me after so many years.

I tried Cooper, 'top of the line'. After 3 weeks had them replaced with the Primacy. Whole world of difference in riding comfort. Even my wife commented on the ride difference. The gas mileage was about 4 to 6 miles per gallon better too. Wow! My Cadillac sure rides like it's suppose to again... Will never listen to a salesman again about tires...You sure get what you pay for...Thanks for a great product!

On a reccent summer cross country trip, this tire was very quiet at excessive highway speeds (80-90 mph). Hitting a few rain downpours on the trip, there was no evidence of hydro-planing at all. I also feel confident with Michelin tires because from my own personal experience, their custome service is the best of any tire company!

I had to come up Route 8 - near the Blue Ridge Parkway last year - wasn't snowing at the bottom of the Mountain, but it was on top. The roads had not been treated and was absolutely terrible - many placed on that road has no guard rails - those tires were amasing - I didn't even slip. No phone reception, no traffic - the tires were a blessing and I won't buy any other

Even though the four tires still have less than 1000 miles on them, I have concluded that under normal driving conditions including a heavy rain storm, the tires handled as claimed by the experts. Though I still haven't had a chance to use them in a Northeast Ohio winter. The road noise is also extremely low as compared to other tires I've owned. And the ride is smooth.

I have just installed a set of Primacy MXM-4 on my 2006 Infiniti M35X. They have completely transformed the ride; the comparison with the original tires is amazing. Road noise is less, the ride is more comfortable and tracking is greatly improved - the car now adheres to the line chosen for it. I also ought to mention that over forty years ago I drove from London to Afghanistan with Michelin Xs on my Land Rover - rough unpaved roads, deserts, mountains on the way, but no punctures and the Xs were still in good order on return. These two experiences are going to be hard to beat. Merci bien, Monsieur Bibendum.

At 2.5 years driving my car and less than 30,000 miles I'm being told I need to replace my Michelin Primacy. I am not a racer with my car and am no disappointed to see many reviews from multiple sites stating the same issue with all makes/models of cars. Not sure I would recommend these tires.

I too have had a problem with these tires on my Acura TL. I purchased them a year ago, and in the last few months the noise level has increased dramatically. I had them re-balanced and rotated and the noise got worse. It's very aggravating to the point where I hate to take the car on the expressway for the loud noise. Is this covered under warranty? Can I return these to the dealer and exchange them? I've always had good luck with Michelins and would always recommend them to my friends, but I don't know if I can last another 2-3 yrs. on these noisey tires!
