Michelin Replaces Primacy MXV4 with the New Premier A/S

Michelin is known in the tire industry and by drivers worldwide for their technology and innovation. In 1946, Michelin produced the first radial tire. In 1992, Michelin introduced high silica rubber compounds and Green X technology. Continuing to develop new and exciting products, this year Michelin released the first tire with Evergrip Technology, the Premier A/S.  

What is Evergrip Technology? Simply stated, it reduces the rate of decline in wet traction. The Michelin Premier A/S retains more of its outstanding wet traction as it wears down. 

There are three main components to how this helps the tire perform:

  • Sunflower oil additive in the rubber compound maintains wet traction even in lower temperatures. 
  • Extreme silica acts to further improve wet traction throughout the life of the tire.
  • Emerging Grooves widen as the tire wears, reducing hydroplaning.

This technology is so effective that Michelin is choosing the Premier A/S as the replacement tire for its top-of-the-line Grand Touring All-Season option, the Primacy MXV4. Already an outstanding tire, I installed the Primacy MXV4 on one of my own vehicles. You can read about my experience with this tire in a post titled, "Best All-Weather Tires for Mazda CX-7."

Why did Michelin place such a focus on wet traction? Keep in mind that accidents are more likely to happen on wet roads compared to dry. Drivers rank the ability to stop when a tire when is worn compared to when new as a top consideration when they're purchasing a new set of tires. The Michelin Premier A/S delivers that additional margin of safety when you need it the most!  

Shop by vehicle to see if this tire is available for your application.

Can I mix both on same car! I only need 2 replacements
Friday, November 21, 2014 by Gary


We do not suggest mixing different tires on the same vehicle. It is best to have four matching tires.

I understand it's better to have 4 matching tires, but I have 2 newer Michelin Primacy tires, and really only need 2 new Premier AS tires. The guy at Sears said they have different turning radii, and I can't mix them. Is that true? I have an '05 Subaru Forester.

With an all-wheel drive vehicle like the Subaru Forester, we do not recommend mixing different tires, sorry.

Interesting; I just got told by Costco Tire I could replace just two MXV4 with two Premiers as long as I put them on the same axle, that is front or rear. This is for a FWD car. I understand it is a more complex issue for AWD / 4WD cars.

I had one of these blow out today that had only 15k miles on it. I have a road hazard warranty so I can get the blown tire replaced free. But is it wise to run 1 new tire and with 3 tires that already have 15k miles on them? Or should I fork over $440 OTD for a set of all new ones?

What is the year and model of the vehicle in question and the tread depths on the "good" three tires?

Yes, the Primacy MXV4 was replaced by the Premier A/S.

Like Bob, I had a blowout on one of 4 new Primacy MXV4s 215/16 I installed 15K km. (10K miles) ago on my 2002 Toyota Camry LE 4cyl and the tire shop if offering one Premier as a warranty replacement. tread depth is 8/32. Is this OK? If not, what is a reasonable position for me to take? 2 matching tires?

Four matching tires is always best. Two Michelin Premiers of the same size and speed rating would be the next best option.

are their any comparison drive test results comparing the michelin primacy v rated all season with the consumer reports top rated michelin premier v rated a/s
Friday, October 9, 2015 by Gary


Unfortunately I have no testing data comparing the older MXV4, but I take Michelin at their word that the Premier A/S is a better tire overall, especially in regards to wet traction.

Due to accident 1 of my MXV4 had to be replaced, they put on a Premier A/S. I'm questioning if this is a good idea. I've always been taught to replace tires in pairs. My car is still in the shop and I am arguing with them about this replacement. They said they were told it was a "Superseded" replacement so therefore; it should be fine. I don't agree. Your thoughts?

I am not aware of any tire manufacturer that recommends mixing tires on the same axle in this way.
