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!

These came on my 2020 Accord Touring 2.0. They're fine for performance and noise, but as with many others, they wore down significantly faster than most others I've had. I'm very easy on brakes and tires (usually beating tire warranty by around 5000 miles). I measure tread depth each time I service the vehicle and at 36,000 miles, tires were wearing evenly, but already down to 4/32 remaining. By 40k (where I'm at now), I have only 2.5/32 tread depth and will replace at my next service. Typically consumers expect at least 50k miles from factory tires, so they come up short in my opinion.

THE MICHELIN TIRES WHICH CAME ON THE CAR WERE RATED TO LAST 40,000 MILES AND THEY DID SO AND A LITTLE MORE. THE TIRES I PURCHASED ARE RATED TO LAST 50,000 MILES AND I HAVE NO DOUBT THEY WILL EXCEED THAT MILAGE. THEY ARE GREAT ON ALL ROAD SURFACES AND WEATHER CONDITIONS AND PROVIDE A WONDERFUL AND QUIET RIDE.

I had the Pilot MXM4 tires on two Acura's TL Tech's and put over 58, 000 on both vehicles before replacing with Pilot Primacy tires. During the period of ownership I never had a sever handling problem, in snow or heavy rain or a out of balance problem. The only thing that annoyed me was the tire noise they created, especially when traveling 1000 miles per day. When time to replace the OEM's I gave consideration to other brands, just based on less tire noise but after reviewing the performance of the MXM$'s I had to stay with Michelin and search for another model tire. Deciding upon the Primacy model, I was shocked as to have such a quiet ride, and then to see the new Acura RLX had the same tire as OEM. Performance of the Pilot MXM4's is gratifying especially pushing them to MY Limits in the Rockies. Truly a superior tire as long as you don't mind some extra road noise.

Just had Primacy MXM4 tires installed on my 2009 Subaru Outback 2.5I Limited. I live in the mountains. So tires don't last to long. I like to drive the curvy bits a little fast. Well let me tell you that I noticed the difference straight away. Smother, quieter, faster acceleration and better gas millage. I used to use a 1/4 tank of gas driving up the hill, now it's 1/8th of a tank. Amazing. I will never go back to the OEM tires again. New tires always seem and feel better. These go beyond that. Buy them, you will love them.

Tires are above average in terms of comfort, ride quality, and traction in dry and wet conditions but suffer tremendously in tread life. Just a little over 28k miles, a bit over half the manufacture's claimed 55k life, and will be needing replacements. Still undecided if I will get these or something else

Car drives nicely with these Michelin Primacy mxm4 tires. I am enjoying the smooth, quiet ride with good handling, tenacious grip on wet roads and long tread wear. I have accumulated 25,000 miles on these tires and they have more than fifty percent tread remaining.

I drive primarily highway. I've been making the 86 mile round trip commute for nearly 14 years. I'm over 250,000 miles in that period on a variety of tires (mostly Michelins). I thought these tires were great in terms of comfort and handling from Spring through Fall. Unfortunately, I only got 43,000 miles on these tires instead of the 55,000 miles for which they are rated (the first time I've failed to go over the treadwear rating). I also found the winter traction to be below-average for the category. It is apparent to me that this tire is highly biased toward touring performance in the dry/wet at the expense of winter.

I leased my Mazda 6; a near top of the line 6-cylinder touring edition in 2009. At the end of 3 yrs. I purchased it. I just replaced the 4 original equipment tires, Michelin Pilots with 4 Michelin Primacy MXM P235/45R18 94V. It's like I'm driving a different car after driving it for the last 3 yrs. During the past 10+ yrs. I've leased a number of sports sedans with Michelin (and other) tires but Michelin tires, in particular these Primacy tires, are the best Michelin tires I've had the pleasure of riding on - ever!

I have a 2WD Lexus RX350. Last year i went to the snow with 50% front and 70% rear on another manufacturer tire. Chain restrictions were in effect. I lied, said it was AWD. (DISCLAIMER: I'm a professional driver and a rescue driver (my job to never get stuck) so i have the experience to drive in these conditions. I DO NOT suggest you do the same. It will cost you your life. The purpose of this is for performance comparison.) Any slight hill, my traction light was coming on. I was climbing slight freeway hills at 15-20mph just unable to get traction. Vehicles were stopped ahead on a downhill and it took 800ft to stop from 35mph. This year, i put 4 new Primacy MXM4s on my SUV. Still had plenty of tread from last year's tires but i wasn't about to go through that again. This year the weather was much worse. Much more snow. On the same interstate, my SUV was having no trouble keeping up with the AWD vehicles and 4x4s. It was so bad, some AWD vehicles (Subaru Outback likely with bad tires) had to put chains on. And braking, night and day from last year. Now, all season performance, my SUV was averaging 25mpg with the old tires. 4 of these and I'm seeing 28-29mpg at 65mph on flat ground. That's a significant improvement.
