OEM tire on 2013 Honda Accord Sport Sedan. Can think of nothing bad to say about this tire. Confident handling in all conditions during two years of all season driving in MI & OH. Never felt timid in rainy or snowy conditions, and I drive somewhat aggressively. Tread wear was excellent as well, having just replaced them after 70,000 miles (3/32" left). Rotated about every 12,000 miles in-line with oil changes. Needless to say, I replace them with a carbon copy.

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

only got 36,000 miles. so not warranty, was ware..having to replace. The cost to do so is really high for no more millage than they get. I have always owned Michelin tires. Thought they were the best tire. Paid less and got more millage Wish I could change the type of tire. The low profile is just not a good tire ..I am 69 and know that I am not racing ,

Purchased this set at 25,000mi on my BMW 525. They have lasted until 90,000 and been excellent in all conditions in our area. We have a tremendous amount of rain and they handle just as well in it as they do on dry road. The only negative is the cost. They have increased tremendously since I purchased my first set 3 years ago.

Bought (4x) new Primacy MXM4s for my 2008 Infiniti G35 xS. These tires are awesome--hardly any road noise and smooth handling in the rain/snow. BTW, live in the Northeast and had my new Michelins' put on right before a major storm. I feel safe again! Anyone thinking about tires for an Infiniti G model, Michelin is your #1 choice.

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 replaced first set of Primacy MXM4 on my 2013 Chrysler 300C with 20" wheels with a brand new set of Primacy MXM4. I got every bit of 60000 miles and could have run them longer. Excellent life if you keep up with regular rotation,alignment, balance, and air pressure maintenance.This is a smooth, quiet high performance tire that I highly recommend for a heavy sedan! I do alot of highway driving during the year. Great highway tire.

I bought the Primacy tires to replace the factory Pilot tires on my '09 Honda Accord EX-L V6. After 5,000 miles I can honestly say these tires are far more superior than the Pilots. They have a much smoother ride, absorb more road noise, and have pretty remarkable wet weather traction. The Pilots were slightly better in handling but I'm much more happier with the Primacy. The physical appearance of the Primacy is very nice and something often over looked.

I purchased a 2012 Infiniti M37X and these tires (245/50R18 ) came with them. I'm shocked to have only gotten 44,000 miles since I take the train every day to work and only use the vehicle during the weekends. The front two tires are completely shot but the rear two look a whole lot better.

These tires handle very well and give a smooth ride. They are a better ride than the stock tires and give less road noise then the MXM4 Pilot Sport A/S. I prefer these tires for casual driving, the pilot sports did have better cornering though. Comfort and fuel efficiency are my two biggest concerns and these give both.
