Not to be redundant I had 50 k on the assurance comfortred and they where fine I did not notice a big difference when I went to the Primacy H. After the Primacy I when I with the new upgraded Comfortred Touring they are better than the primacy these tires are sweet.

Maybe I am missing something but why would you go back to a tire that was noisey at "a couple oil changes shy of 28k", had flat spots that disappeared after a mile or so and where really annoying? I never have problems with Michelins and Goodyears and they last usually the warrantee period. THX Warm

 

Unless you have a sound meter to measure it objectively, everyone is going to think differently of the sound level. I just got the Primacy coming from Contipro Contacts and they are about the same. the Cl with dual pane glass is so quiet I can't make out much noise from anything.

 

Any car I have with Michelin tires on it will develop flat spots if it sits for a couple of days. They quickly work themselves out. This is only happening with Michelin's I have purchased in the past 5 years.

I have the standard 17" 6-spoke wheel with my LS. I had gotten a '02 16" three years ago to mount Blizzak tires on and after three seasons, I decided that I never really drove my LS in snow anyway, and with an RX and MDX sitting around, I doubt I'll ever need to drive my LS in snow anyway, so I swapped out to Primacy with the 16" to give it a try. Honestly, very quiet but too floaty. I'll be going back to 17" after this set wears out.

Hey, the 17" would have been $184, while the 16" were $150.

 

I drove my car today for the first time since the dealership changed out the Primacy tires and replaced them with the Pilots. The Pilots are not as quiet as the old MXV4 they replaced but they are much quieter the Primacy.
I hope my experience isn't an indication of where Michelin is headed. Some of us still want a soft ride and as little noise as possible.

 

Thanks for the update! Did the Pilots seem to be crisper/handle better than the MXV4's and the Primacies?

The MXM4 rated the best of four on TireRack in their testing,

MXM4, Conti Procontact, GY Comfortred Touring, Serenity on Tirerack so the MXM4 must be there quiet cruiser now(not sure what size they tested). Too bad it was not in your size

 

I do not think I have had enough experience yet to give you an opinion beyond they do not have the roar of the Primacies. I will post more later when I have had a more experience. What puzzles me most about this enitre ordeal is a number of people got completely different results with both of these tires and we are all driving the same car. I believe each owner reported what they experienced but for whatever reason those experiences were often different. For me the Primacies looked like truck tires and rode like truck tires. What bothers me the most is the person I reached in Michelin management seems to believe the days of the quiet Michelin are gone, at least in this class of tire for the time being.

 

There are lots of Michelin Pilots and they're very different from one another. Which do you have, the Pilot Primacy, Pilot MXM4, Pilot Exalto, Pilot Sport...?

 

Pilot HX MXV4

 

How are those Michelin Pilot HX MXM4 tires work out for you? Anyone else uses them on our cars, and what do you think? I'm thinking about getting those on my 18". Thanks.

 

I just came off of a set of Primacy MXV4s and put on a new set of the same. The old ones were smooth and quiet which is why I wanted another set of the same. The new ones are just as smooth and quiet. I think your situation is unusual for the MXV4. I would return them for a new set.

 

Oops, my bad. DNC had Pilot HX MXV4 on, not "Pilot HX MXM4".

Anyone has experience with 18" Pilot HX MXM4 on our cars? Thanks

 

I have used Michelins for about thirty five years. First on a Chevrolet Impala 454 sedan, through a Mercedes 500 SEL (sorry - edited because spell checker has a mind of its own), and now on both a 2009 and 2012 ES350. First, there is about a 500 mile break-in. (My M-B tires were always the highest speed and heat level and I was lectured by a French factory rep about break-in and "time to adjust" periods back in 1986.)

Since this is my first post here, and I found my way by Google since my dealer supplied me with neither warranty book or instructions, I think some folks are not properly informed.

I took six months to study every aspect of the four versions of the MXV4 and a couple of other options, but kept coming back to the MXM4. Had to fight for a price and to convince them that that was what wanted. The first 50 miles or so, there was a little humming. And when exiting the car, you could smell the "hot rubber" smell. After the first 50 miles, now beginning to smooth out. Side grip is great. (Don't drive these cars like I did the 500.) The mechanic for two M-B and a BMW 528i always counseled to take time to let them break in, particularly the "heavier" the tire. If you don't spend the extra money for all-wheel alignment and have the rims inspected for any wear that might cause off-center dynamic rotation, you are not taking care of business.

I think the MXV4 is a great tire. Hope it will serve you well.
