In my 20 years of driving these are the first run flat tires I've ever had and I would never purchase them again. Since I've been driving I've never had a bubble or tire ever shred on me until I bought this car with these tires. On this car I've had an issue with all 4 of the original tires. 3 of them had bubbles and the 4th was going to shred. With run flats I thought they were supposed to be more durable but I've found that to be the opposite. When the last one developed a bubble before I went on a long trip I called everywhere and they were on national back order and the only place I could get the tire was from the dealer which ended

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.

Michelin Primacy mxm4 tires are very competent on wet & dry conditions in summer and are even pretty good in snow IF ITS COLD..but in wet snow / slushy city roads these tires are HORRIBLE. I chose these for my sister's Subaru Forester as I was very impressed by the Michelin Pilots I had on my Camry, but the Primacy mxm4 are very disappointing. I'm now shopping again, this time going for an ALL WEATHER TIRE. I'm not sure I will be purchasing Michelin's in the future. This vehicle is used primarily in the city and she didn't want to have to invest in two sets of tires considering she drives less than 10k a year.

Tires are very quiet, great handling, and with great traction on snow and ice. Handles turns like a champ. However, after 57K miles and 2 weeks past 6 years and with a healthy amount of thread left, noticed a crack developed in one of the tires. The crack is in a place that is very hard to be in contact with foreign objects in the road. Now I got to replace 4 of them because of that.

I have Michelin Primacy MXM4 245/ 40R/ 19 tires on My Lincoln MKZ. Tires are great except after car sets for a few days the tires seem out of balance for the first 5 or 6 miles. After that they are great. It has always done that. These are OE tires and now have 9500 miles on them

My original tires were an OEM Michelin. I was satisfied with them but wanted to upgrade on my next set. I went with the Primacy MXM4. They were excellent! Great steering response, never made any noise, never needed to be re-balanced. I rotated as you should but was able to run them 92,000 miles. They still had serviceable tread but I decided I had gotten my money's worth. I put on another set last year and my 165,000 Crown Vic still feels like it did when I brought it home in 2004. I'm now putting a set on my Challenger RT.

The Michelin Primacy MXM4 have been the best tires all around I have owned. I drive 40,000 miles a year in all weather conditions from mountain snow and ice to heavy Oregon coastal storms. I have mismatched front and rear tires on my Mercedes CLK and the rear tires currently have 42,000 miles on them but are getting close to replacement in the next 3-5,000 miles. The front tires have more than 50% tread left at 56,000 miles. The last set of MXM4 tires on the front were changed out at 80,000 miles. The MXM4 tires stick to the road like glue on hard cornering. These are impressive tires!

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.

These tires came on my car when I purchased it new. I was excited to see that it came with Michelin tires, assuming they would be better than some of the lesser-known brands that come on other new cars. To their credit, I would like to say that I live where it rains a lot and feel like they are pretty competent in wet weather. However, my car is currently at 46k and my most recent service indicated they are all at 4/32 and I will be planning to replace them this fall. We don't get significant snow, but they did not inspire confidence the last two winters. I have had several other all-seasons in the past that I've never doubted in our short and mild snowfalls, but I would not consider these an option. I am also very surprised at the tire wear as I believe these have a 90k warranty? Overall would not purchase again and will be looking into other options.

I've got 34,550 kilometers on my Buick, and the dealer told me on my service check-up and oil change sheet that I'll need tires very soon. I'm 74 years old, so I'm not hot rodding around that's for sure. Hard to recommend a tire like this, I understand things happen, so I leave it with you. ps: This car is parked in a heated parkade when not driven.
