I replaced the stock tires on my Chevy HHR with four Michelin Primacy MXM4s. The two most impressive things to me about the tires was the balancing of the wheels/tires and the handling. After mounting the tires to the wheels I found that the weights needed were minimal. I recall one 0.25oz and one 0.5oz were used on one wheel and the change from that throughout the remainder of the tires wasn't much more if at all. The only reason this popped out to me was when removing the weights from the wheel with the stock tire, there were four 0.5oz weights on the inside and some weights on the outside. I can't remember exact amounts (changed tires about 20k miles ago) but it was very noticeable. It was roughly 4-7 weights off and 1-3 weights on, and this factor alone helped to give me confidence about the quality of the product. Concerning handling, I obviously don't drive a sports car but the feeling on the road came into existence. The stock tires had no feedback but with the Michelins it was as if you could feel all four tires when swerving back and forth. Other aspects of the product that impressed me was that the Michelins were quiet, and the tire wear is not too bad seeing that I finally rotated my tires after 20k miles (forgot lol). I drive approx. 60 miles one way to college via the I-10 (no dorm), so I was able to see the difference in the tries relatively quick. I usually go the speed limit or whatever traffic allows (75mph-83mph). Really no complaints at all. Probably the only complaint I'd say would be the price, but you get what you pay for.

Bought a set for our 2014 Charger RT 62000 miles ago!! Just now in the wear bars. Going after another set! Will mention its very hard to get the 70 dollar chard back as a rebate we waited MONTHS with several calls the last time!! The tires are awesome in Rain! No planning! Very quiet and smooth. Actually they are worn out still are better than the goodyear eagles were as a new tire when we got the car!!

Would give Zero stars if possible. These tires came with a new Model 3. 23,323 miles later, constantly properly inflated, driven conservatively, and they are near bologna. These are THE worst tires manufactured since the steel belted radial in the 70's

Best tires i ever purchased, you know when you put on a set of tires and you get in the car and drive away from the store you just bought the best tires available, these tires ride smooth, make no road noise and look incredible on the car, thanks Michelin for making a great tire.

I live in western Pennsylvania and work in eastern Ohio -- need I say more regarding our weather? I have always been a white knuckle driver when it came to our winters. Snow and Ice --- scary stuff for me. But my new Michelin tires take me safely to and from work (30 miles round trip) and I always feel confident that they will keep me on the road and able to stop and start safely. I think that this is my 4th set of Michelin tires and I recommend them to everyone.

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

These Tires were original to my FWD 2014 Buick Regal Turbo. Rotated every 5K miles. They were comfortable, decent performance and overall good tires. I recently replaced them with Continental Extreme Contact DWS06 Plus. These last a good long time, 100,000 miles, 50,000 miles each tire on the drive wheels which is right on par with the warranty. The reason I didn't purchase these again is because they are really expensive. I understand that they are touring sport tires so they have to be both comfortable and have good performance and tread life but when i switched to the continentals, the new tires were just as comfortable even though they're ultra performance all season. These tires run even more expensive than the critically acclaimed Michelin pilot sports. The MXM4s also have pretty thin soft side wall, maybe for comfort but it was flushed with the rim so no protection from curb rashing the rim. The rubber compound is softer which makes for great stopping in wet but the trade off is they don't last as long as rivals, especially for heavier vehicles like EVs. Overall a Good tire, but for the money you can buy a tire that offers more for less, including offerings from Michelin.

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.

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.

Primacy MXM4’s were factory installed and gave very good service. Very smooth and quiet, not a hint of balance or out-of-round issues (I’ve seen that). But coming from a 2WD minivan with good winter tires to a AWD SUV with new All Season tires in a major snow belt area was scarily disappointing, but nothing a new set of good winter tires couldn’t fix. Winter tires with 2WD is better than AS tires with AWD on snow covered roads with any accumulation, but winter tires & AWD for the win in really bad conditions. Changing tires every winter makes it more trouble than it’s worth to keep track of mileage on each set, but after 260K kms, I’ve used up the original set, a set of Premier LTX’S and about 66% of the winter tires. Not bad at all. Both sets have been very good. Both were very good on wet roads, with the LTX’s staying excellent right until they were down to the wear bars. And the MXM4’s become quite noisy and more slippery close to end of life, but nowhere near as bad as some others I’ve experienced. All in all, the 2 best sets of tires I’ve had. Getting a new set of MXM4’s tomorrow.
