Michelin Primacy MXM4 or MXV4

Is there a reason why I see a lot of recommendations for the MXV4 and not the MXM4?

MXM4 seems to get better gas mileage and is a lot cheaper... just wondering.

The MXM4 is a little sportier as far as performance goes. When i worked as a tech at a honda dealership, the MXM4 is what we put on cars like the civic Si and S2000 . The MXV4 went on the family cars. They are quieter.



Edit : Yup, i mixed em up lol. Been awhile.

Actually....

You have that backwards...

The MXM4 is the sticker of the two...

MXV4 is slightly quieter and "should" provide a 1MPG gain over the M4...

So, M4 if you want more traction(in the dry)
And V4 if you want longer tread life(at the expense of a little less dry traction)

MXM4 is V rated, 55,000 mi warranty, and is designated as a low rolling resistance tire.

MXV4 is H rated, 60,000 mi warranty, and is not designated as a low rolling resistance tire.

Just on that I would think the M4 is softer and stickier of the two based on the warranty.

I would think that the M4 would provide better mileage as it's a low rolling resistance tire which doesn't necessarily have to do with grip/softness of the rubber.

The MXM4/V4 is...

An oddity...

The fact they BOTH exist is weird. And the "Green X" technology exists in both...

When you find the same size tire where they are both "Green X"(doesn't happen in all sizes) the M still has less tread wear life.

But that is the problem with the 225/55/17(not sure if that is the size you need)...

The M4 IS Green X, the V4 is not.

Even worse, there's an MXV4 PLUS which does have the green X LRR, but it seems those are on closeout and are even more expensive than the regular V4's.

and one would think the V4's would be V rated, but they're not...only the M4's are.

Another tire...

Provided you can find it, that I would rank as the best of both the M4 and V4 is the Fulda EcoControl.

But...finding a place that sells them...not easy. Fulda makes great tires.

Several of the Michelin MXV4 tires are designated as Green X / LRR (select "Sizes" tab). It earned top marks for LRR in Consumer Reports' test of size 215/60R16. It also scored very well overall in Tire Rack's test of "Grand Touring All-Season" tires.

We were very impressed with the MXV4's performance on our 2006 Accord.

To add to what Crewzer said...

The "toaster on wheels" (as some people call the Forester), unless you upgrade the suspension bits...

I don't think the M4 is a worthy trade off from the V4. The "suspension giving up" is the main determinant of when tires give up.

If the M4 creates even .01 more G in cornering...I'd be shocked.

If you had a turbo and you drove aggressive and/or lowered your car, then you might have a case for the M4.

Or if I wanted to save $100 for no real difference in performance?

For what its worth for anyone searching, I ended up getting a massive blowout on my old set of tires and got the MXV4's because I was in a pinch and none of the local shops could get the MXM4's. I have to say I'm fairly disappointed in the MXV4's.....think I should have listened to MikeDrives instead of Schan. I think they're just too soft of a tire. The grip is fine, but they feel too floaty and disconnected from the road for me. I feel like I'm bouncing around on the road and constantly have to correct them on the interstate. Body roll is really noticeable. .... and that is with the set aired up several PSI high.

Unhappy

I'm sorry to learn that you don't like the MXV4's. I "need" (want) new tires for our BMW, and MXV4's were on my short list until I found I can't get them in the correct combination of size and service description (225/50R17 94W).

It looks like we may end up with the Primacy MXM4 is that size, although the "W" speed rating spec (168 mph) is asinine.

Best of luck!

Good info. I bought MXV4's for my '08 Civic. I thought they were fantastic tires. My brother had a set on a '05 Accord, and thought the same. I figured some of what I don't like about my '12 Forester could be fixed with a set of them. It did bug me that they are for Camry, Accord,etc. And also that the Geolanders on my Forester are very highly rated tires, made me wonder if I might be looking in the wrong direction.
I don't see a ton of tires that show up for my '12 Forester when I search tire sites online. If you go with "all tires in this size" you get a big list, but you are looking at Camry tires again....

Yea, as with any tire it really depends on your personal preferences and what you're used to, so blanket "these tires are awesome or these tires suck" comments are tough to judge. My wife would think that if the tire is black and round its great. :) Obviously, I need a more connected tire, probably a sportier tire like a high performance allseason. If i were to do it again, I would probably search out the MXM's.
