Primacy 4 2S came with the new car. Useless on water, noisy as heck. Will not buy again.

Terribly disappointed by these Michelins. A-class rolling resistance tires demonstrating fully the challenge of low rolling resistance designs. Rut sensitivity so bad it’s basically dangerous. Very poor comfort as well due to excessive shake. Steering is delayed and non-linear. Plan to replace next summer after only one season.

This is a review comparing it to the summer tire Michelin Energy Saver that I used last time.
The vehicle installed is a late 2011 Toyota Wish 1.8S with a current mileage of approximately 270,000 km. The average annual mileage is approximately 22,000km, including 14,000km on summer tires.
Due to the snowy terrain, we used three types of tires: summer, all-weather, and studless. After use, they are cleaned, maintained, covered, and stored in a tire stocker in the garage.
In the summer (no snow season), it's summer tires ➔ In early winter (snowfall season - before the snow compaction road), it's all weather ➔ In the middle of winter (snow compaction road - icy road), it's studless ➔ In early spring (ice melting road - before the end of snowfall), it's open Ruler Weather➔In the summer Samataiya

Dry and wet grip: I felt that the grip of the Energy Saver had decreased after 40,000 km, but I felt that the grip of Primacy 4 was almost the same after 40,000 km as when I first started using it.
Tire wear rate: The mileage at which the slip sign appeared was 50,000 km for the Energy Saver and 55,000 km for the Primacy 4, which is 10% better.
Comfort: I felt that the Primacy 4 was superior in terms of comfort at the time of purchase, but after driving 50,000 km, I felt that both cars were noisy. Comfort seems to decrease in proportion to driving distance.
Repurchase: Currently, the plan is to repurchase Premacy 4 again. The reason is that the initial grip performance does not change for a long time, and it has high wear resistance and long life.

In the dry the Primacy 4's been excellent. Grip feels almost infinite, to the point where I find it hard to use all of it on public roads. In terms of comfort, it's a quiet, pleasant tire to cruise with. At highway speeds up to 180 km/h I can't really find any fault with the tire. It's relatively quiet and absorbs enough of the road to almost feel like driving on a cloud.
In the wet the grip is still above average, much better than my current winter tire (Vredestein Wintrac Pro in the same tire size). Comfort and noise levels are in check, although it's harder to judge noise with all the extra noises introduced by the water on the road.
One thing I sometimes miss is communication during turn in and feedback from the road. I guess this could be party because of the relatively meaty sidewall but to me it was noticeable enough to point it out.
Regardless of that downside, overall a great tire that suits the characteristics of a 5 series well.

Michelin primacy 4, with 360 treadwear rating can reach 50,000km/ 5 yrs. Pass that and it start to have crack lines on its sidewalls and remaining soft treads starts to peel. Its rubber compound doesn't stand well in the tropical weather. At least till the above mentioned points. Quite good mileage, but other reputable brands also last till 50,000km too but they do not peel like this model.

A comfortable ride up to maybe the 4th year. Very good grip as well.

Sidewall looks good after years, does not sag, maintains its sporty low profile look. Cheaper ones sag the moment you fit them in. Gives you the under inflate look despite the correct psi. Primacy 4 does not sag.

I bought Primacy 4 just after when i bought my Seat which had Potenza tires. They was horrible and Michelin at that time (4 years ago) was still better. However after 4 years and 40 000 km later i can say that Primacy 4 are at most average. Ok, hadling is good or even very good, but comfort is totally crap. Tires are loudly basicly since 40km/h and trasfer vibration from road to car. I could live with that but the worst is loudnes of those tires. I swap front with rear tires side by side - nothing help. I know that Seat is loud car but my freind has same rims in his Seat and have Goodyear and it's much more quiet. Today even i went to tire shop to check whats going on and specialist suspects many things but probably i will change tires for Bridgestone or Goodyear. i realize that profil 40 is not the most comfortable but come one.

I honestly don't recomend. Gum is to hard for comfortable riding in Seat Leon and with time getting louder.

Review on 4x Primacy 4 ST. Overall very happy with them. No complaints with grip, stopping distance, feedback and handling. The wear is phenomenal, I am on 75000km and there are at least 2.4mm tread left on them. Some people mentioned about the tires being "slippery" when new - yes, I encountered that too, well at least for the first 2000 kms. Most pronounced when driving fast whilst turning -like getting off an exit ramp at a freeway. The noise level is getting louder (vs when new) but that is to be expected with the kind of mileage they are on. Overall, I had Contisport Contact 5 and Pilot Sport 4 fitted on the same car before the Primacy. I find the Primacy to be the most satisfactory amongst them. The only gripe - they are expensive. I will buy again if the price is more competitive.

I've had these tires on from new and honestly, I'm not that impressed. Both me and my wife have the same car, except hers came on Goodyear Efficenct Grip Performance and mine came with the Primacy 4's. They handle perfectly in dry weather but in the wet, they feel very squirmy and unsettled. I've frequently provoked wheelspin on junctions and during acceleration on roundabouts in wet weather. They are also wearing poorly, at 13,600 miles, they have 2mm of tread left on the front and 3mm at the rear. The Goodyears on my wife's have 21,000 miles on them, and are at 2mm. The Michelins also ride much harder than the Goodyears and are louder too. Overall they are just about okay, but I wouldn't pick them over the Goodyear or Pirelli equivalents, especially when they are considerably more expensive.

i have being usung michelin for 50 years here in s africa my latest tire primacy 4 on my old mercedes 190e well its a different car tires very smooth and noiseless and in wet exceptional coupled with 190e suspension perfect match

I've used these tires for about 3 years, great braking distance and good handling in both wet and dry. I'm an average driver so ymmv.
what i really like is the handling remained more or less the same from new to about 3/4 way of the tire's life. now that it's 50,000km in i can start to feel a little less grip that before, just a little.. maybe it's a mental barrier since i know the tires are nearly bald in the rear.

This the best tire i ever had. Really good handling in dry and wet. Good aquaplanning reduction effects. Mostly i will change my tire maximum every 50.000KM, but this tire still good until more than 60.000. I use it for 3 years until now and still in good condition. My negative comment about this tire is only about overprice. It's very expensive for non-RFT tire, almost 2 times than other brands.

I have to say right up front that i regret fitting these tires to my car , having heard many good things about the brand i wanted to try it out and did so without really looking much into it (which i regret now).
I drive a lot on the motorway and these tires as other reviews have said are extremely soft , so much in fact that the car gets easily affected by crosswinds (which mine never did before) , and they have a constant floaty sensation that really does not inspire any sort of confidence , feels like you are driving some sort of barge on a river. As for hard cornering being a soft tire they flex a lot on hard cornering to the point of feeling unsafe again , the grip itself is just ok meaning the car wont really fly off the corner but it sure feels like it will, also on hard acceleration on uneven surfaces like cobblestone streets or something it will just spin and feel really bad. This is not to say this tire is unsafe but it FEELS unsafe , the squirrely feeling on the highway , crosswind sensitivity and such really makes for a white knuckle driving experience.I really want to stress the negatives because really it surprised me having heard all my life that Michelin makes the best tires on the market (the cost sure is up there) , it came as a shock to me how bad they performed when fitted, being a touring tire and all i thought they would excel at highway driving but they in fact did not.
There are however some positives that maybe could work for you , if you exclusively drive on city i don't think they will bother you none, and the wet grip is better than average to be honest , i believe you can get some 40 or 50 thousand kilometers on these tires , being soft they will be comfortable over bumps provided you don't drive fast. The price may be an issue as they are not exactly cheap tires you can just fit and don't feel bad about spending money on it, if you really want to try them out and see what the fuss is about i say wait for a discount as they can be found cheaper sometimes. Maybe some cars will also accept this tire better and feel just fine, maybe it would even be an upgrade for some cars but in my case it really didn't work out.
