The Primacy MXM4 is Michelin’s Grand Touring All-Season tire developed for luxury sedan and coupe drivers looking to combine all-weather handling and traction with good noise and ride comfort. Most Primacy MXM4 tires meet Michelin’s Green X standard* for eco-focused manufacturing and low rolling resistance, and confirms the tire’s contribution to reducing vehicle fuel consumption, emission of CO2 gases and improving sustainability through conservation of natural resources. The Primacy MXM4 is designed to blend a quiet, comfortable ride, responsive handling and enhanced fuel efficiency with year-round all-season traction, even in light snow.

The Primacy MXM4 features Michelin’s first use of their patented sunflower oil-enriched Helio Compound technology in an all-season tire to increase traction at low temperatures for improved braking and handling in the wet, as well as better overall performance in the snow. The Helio Compound is molded into an asymmetric tread design featuring a European handling profile with rounder shoulders that are designed to provide progressive, predictable cornering. Circumferential grooves evacuate water out from under the tire’s footprint to reduce hydroplaning while Michelin’s 3-D Variable Thickness Sipe Technology provides additional biting edges to enhance wet and wintertime traction.

The Primacy MXM4 was developed with Michelin Comfort Control Technology using computer-optimized design and precision manufacturing methods to reduce vibration and road noise. The tire’s internal structure includes twin steel belts reinforced by Michelin’s BAZ (Banded At Zero) spiral-wrapped polyamide cord that stabilizes the tread area to enhance treadwear, handling and high-speed capability. The Primacy MXM4 features a polyester cord body to provide a smooth ride.

  1. 2013 Buick LaCrosse AWD with 71000 on the original set of tires. They have looked like they’ve needed replacing for a year, but honestly, they still grip well in rain. I’m actually surprised that they still have the grip they do. We live sub-urban and drive about 5 miles of country road before we hit the stop lights of the town. Like everything with that Buick, these tires support everything that is smooth, quiet and comfortable. I’m not going to try to get any more out of these during the next winter season. You win, Michelin. I’m buying a replacement set – I don’t know how I could get as lucky with a different set.

  2. I have been driving Mercedes and BMW’s hard since 1985. I’ve owned 5 Mercedes E’s, G’s and C’s. I bought this E320 4MATIC for my elderly mother to replace her Nissan. After buying the car I drove it from the SF Bay Area to her home in western Kentucky with my family. We took the longest twisting scenic route through the Rockies and I definitely put the car and these tires through their paces hard. At home my wife and I have a 2016 and a 2018 Mercedes both with much more expensive rubber. However I am frankly shocked at all aspects of these tires. Despite my pretty much shameless and wanton abuse the tires are performing remarkably well. They show zero wear and I have thrown them around some of the most challenging roads in the country. I was concerned at first because of the mixed reviews. However they’re handling far better than many other tires I’ve owned. We live in the mountains in California and so burn through tires pretty quickly. These tires are awesome for touring and exceptionally quiet as well. These tires are frankly made for a Mercedes sports sedan and are capable and comfortable on dry straight ways as well as twisting mountains roads and rain. On the way east we were hit with severe weather: sudden downpours and flooded highways. At one point there was standing water and a truck next to us was having control problems in the water on the highway. The tires gripped the road well with zero hydroplaning. The rain and splashing from other vehicles was so bad on a mountain passthat we briefly lost visibility. I’m very thankful for the high quality and wet weather performance of these tires. These aren’t track tires but frankly they’re far higher performing than most people are giving them credit for.

  3. Bought my Acura TSX as a lease return with 55,000 miles on it. Michelins looked to be in such good shape, I thought maybe they were replaced by the first owner. I realize now that these puppies can go the distance! I am at almost 97,000 miles (156,000 km) and I’m nearing the wear bars at last. These are good handlers in the dry, and passable in the wet. Recent hydroplaning incident has me looking at new rubber, though. Light snow is do-able, but anything over a few inches has me leaving it in the garage and taking transit to work. One thing I’m really impressed with is the tires’ quiet demeanour, even when it’s close to used up. Have to admire the design and construction. However, these will be replaced with Sport A/S 3+ tires because I’m looking for more traction in the wet. Weather events these days are getting nastier!

  4. These tires came on my RWD Charger and the reason I suspect so many manufacturers use these from the factory is because of how quiet and comfortable the ride is on them, good way to make your new purchase feel nice. Other than that these tires have been pretty terrible, especially factoring in the ridiculous price. Perfect conditions and they do a decent job but during heavy rain there was more than a few times the rear end stepped out and two memorable hydroplane instances. More than a 1/2″ of snow? Fuhggeddaboutit. Absolutely useless though to be fair they weren’t really designed for snow, make sure you have a set of winter tires when getting these!

  5. Great tire that came standard on our 2012 AWD Charger RT. Have about 61,000 miles on them and they are ready to be replaced. I was not the best at getting them rotated regularly and they still held up nice. Pretty good in the snow and ice. Overall great tire.

  6. Shocked when these tires are at the wear bars after only 20k miles. Looking at specs, this is the expected lifespan in my use case. This is a daily driver, fair amount of stop and go, no freeway/interstate to speak of, mostly state/county roads going from stop light to stop light. Average speed of 35 mph. Different size tires in front/rear seems to cut life of these in half according to manufacturer’s documentation.
