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.

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

These are the best original equiment tires I have used. They are on a 2009 Acura TSX and enhance the car's already good handling, in my opinion. The only comloaint I have is that, at least with this car, they are a little noisy. I view this as more of a probl;em with not enough insulation on the Acura, and I suspect it is triggered by the low profile of the tire.

I have bought Michelin tires in the past for my SUV but have since sold the SUV and now have an AUDI. I am so glad I replaced the tires with Michelin Primacy MXM4's, they handle much better in the Florida rains and are much quieter and when stopping quickly I stop much faster weather it's on wet or dry surface

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.

On our trip from Pittsburgh, PA to Sarasota, FL in September 2012 and traveling through West Virginia in the rain the second vehicle (Ford F-150) ahead of us did a 360 and hit the concrete barrier traveling at 70 mph + we were able to come to a controlled stop without any fears of hitting the car directly in front of us or the F-150. I believe the MXM4's were the reason for the safe controlled stop. THANK YOU Michelin!! PS: The driver of the F-150 was OK but, the front end of the truck was a mess.

I am so much more happy with my Michelin tires than my previous tires. QUIET - I wanted a good performing tire that was quiet. I have a long commute to work and wanted a tire that would last and that was not louder than the radio. I'm glad I chose to go with Michelin tires.

I have purchased this tire several times in my car owning history. I love the way my car manuvers and holds the road. They are a bit pricey but I know the tire and it is tried and true. I also like the fact that there is less road noise from this tire than others.

I've been purchasing Michelin for years and could not wait for the OE tires to wear out on my vehicle. The new Michelin Primacy MXM4 did not dissapoint. The OE tires were noisy and these new Michelin tires have much less road noise on the same daily traveled roads. I also appreciate the excellent dry and wet weather grip. During some heavy rain I had full confidence as if it the conditions were dry. The Primacy series offers what I need... great handling, smooth ride, excellent bad weather grip, and low noise. All my Michelin tires have always lasted at least 50,000 miles and sometimes over 60,000. I'm sure these will also give me years and miles of driving pleasure.

I have purchased Michelin Tires for the past forty years. Once or twice I tried other supposedly top rated tires only to be disappointed. They came no way near matching the quality or were able to endure the road conditions like my Michelins. With Gas prices on a constant increase; I have found that I get an average of 3 to 5 more miles per gallon of gas with these premium tires. You could not get to change Brands. Michelins are Fantastic
