On a reccent summer cross country trip, this tire was very quiet at excessive highway speeds (80-90 mph). Hitting a few rain downpours on the trip, there was no evidence of hydro-planing at all. I also feel confident with Michelin tires because from my own personal experience, their custome service is the best of any tire company!

I bought Primacy MXM4 tires size 225/50/17 for our 2009 Audi A4 and I couldn't be happier. These tires are quiet, smooth and comfortable and make this car feel like the luxury sedan it is. They handle dry, wet and snow-covered roads with ease. We have about 11000 miles on these tires and there is very little wear. I will not hesitate to purchase or recommend these tires in the future!

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

I have these tires installed on a 2005 Mazda6 for a year now. Generally use the car for daily commuting and the occasional long distance trip. The handling in wet and dry conditions are excellent and the tires absorb the road noise very well. The ride on the tires is exceptional at highway speeds. I would definitely recommend these tires.

I SPECIFIED MXV4 WHEN I CONTRACTED TO BUY TIRES BUT CAR WAS DELIVERED WITH MXM4. I RESEARCHED AND DECIDED DIFFERENCE WAS MINIMAL AND WOULD LIVE WITH MISTAKE. NOW,AFTER SOME MILES OVER FAMILIAR ROADS I AM IMPRESSED WITH THE IMPROVEMENT IN RIDE,HANDLING AND ECONOMY THESE TIRES OFFER,AND AM HAPPY WITH MY DECISION. i HAVE BEEN DRIVING ON MICHELIN,ALMOST EXCLUSIVELY, SINCE 1959 AND HAVE ALWAYS BEEN PLEASED.

I just purchased these tires for my Kona EV. They are more quite than the original stock tires, but I noticed a big decrease in the MPe of my car. I would average around 4 and now it is down to 3.5. I am not sure why but it does decrease the mileage per charge. They definitely grip better and are quite.

I purchased a 14 Avalon xle touring with these tires on it from factory. I've had the car for a little less than a month and these tires give the car a very comfortable ride! I can't speak on the tread life for only having it for such a short time now but I use to have the Pilot MXM4 on my 11 Accord ex v6 and the tread lasted very well for daily spirited commutes to work. I recommend the Primacy and the Pilot MXM4 for anyone looking for a quiet comfortable ride without sacrificing handling, traction and performance.

These are my 3rd set of Michelins for my 2007 Toyota Avalon. The first 2 sets were "Energy". I switched primarily for longer tread life and lower price. I now have about 10,000 miles on them and the Primacys seem to be just as good as the Energy-so I feel I made a good decision. They are just as smooth and quiet. Gas Mileage is about the same. The cornering seems good even those these are "H" rated vs "V" on the Energys. I don't do much racing so for my purposes "H" is fine. I would but these again.

These are the best handling tires I have ever used on my car. In the last few months I have had to brake fast and swerve to avoid hitting a deer. The car was able to stop before reaching the animal. I believe we avoided an accident because of our Michelin tires.

I bought these tires after using various brands over the years. I must say that they perform better than any tire that I've tried in the past. I drive a 9 year old lexus ls 430 and have had several set of tires on this car and these are the quietest yet most responsive tires of all. I'm really impressed.
