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.

Occassionally due to auto manufacturers choices or recommendations I have used other brands of auto tires. They always seem to disappoint me. It is usually the ride, handling, miles-per-gallon, or total miles driven on the tires. I then switch the vehicle to Michellin tires and I say "thats what I've been missing!!"

I bought these tires on Saturday November 20th and left the next day on a 2200 mile round trip. I was very impressed with the quietness of the tire. The handling was great. However, the mileage on my 2010 Prius decreased by 5 miles per gallon. This is very disappointing. If MPG is not important then I recommend this tire. For the Toyata Prius it is not a good choice.

Review of Primacy MXM4 after 6 years and 84,000 miles. Best tires I've ever owned. Tires are on a 2003 Infiniti I35. Excellent in all areas: wet, dry, highway, around town, even treadwear on all four, and always quiet. Now worn to 3/32". If you have a newer sedan, and can still find the size you need, buy them.

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 the tires in 2010 (it is now 2013) and they have been great. My car used to handle horrible in the snow and also the ride used to be quite rough. Since the new MXM4 tires the car feels much better, handles excellent in dry, wet or snowy roads. No complaints at all, highly recommended!

I have been driving on these tires for a little over 9 months now and they still look new. They are on a 2006 Cadillac DTS Sport and replace the OEM tires. The improvement in handling, ride comfort, and quietness was dramatic. These are easily the best tires I have had on any vehicle I have owned in over 30 years of driving. The low profile makes the car look sharp and the ride is smooth and quiet with very good responsiveness to acceleration and lane changes. This Caddy can push the tires when running in sport mode -- the active electromagnetic suspension coupled with these tires makes for confidence when a little aggressiveness is called for. I spent a lot of time deliberating about what was "good enough" and realized that for just a little more I could have the best. I have no regrets and these will be my only choice for the long run.

Best all season tire yet! I've had them for approx. 18 months... great handling year around especially during the Winter months here in the Midwest. I did opt to go with P245/45R17 instead of P225/50R17... a bit more rubber on the road which made a major difference. Prefer them over the Pilot Sport A/S Sport.

We bought our car with Michelin tires and when it came time to replace them, money was an issue and my husband went with a less expensive tire with me having a fit the whole time. Oh my gosh what a mistake he had made and I was the one who had to deal with them. They were terrible with road noise and anything else you could imagine. They did not last-which was bad but great for me because I stood firm and said NO other tire but MICHELIN!!!! When they were put on, I thought I had died and gone to Heaven. My husband finally admitted he made the mistake and he could tell the difference as well. By the way, my boss rode with me one day with the old tires and ask what in the world was wrong with my car. Mind you, I drive a Acura which in itself is a nice ride!! Michelin always from here on out!!!!

How do i love this tire, let me count the ways... I could not have felt the pleasure of cruising up the pacific coast highway on any other tire. The Primacy MXM4s just have a way of letting me take those turns while I take in the views of the pacific. I haven't had them for a long long while but so far these babys are not letting me down and if they live up to the warranty and other reviews i've read this is a tire i'd strongly recommend if it fits your ride.
