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.

No complaints about the overall performance. However, despite a 70dB rating, as they wear down they become very noisy on anything less than a very smooth asphalt road surface. Will not buy again for this reason.

They are expensive, but at least they last for a very long mileage. They offer good grip in any road condition,For most aspects a great tire: very good comfort, silent, great cornering, very good wearing. My problem with them is the vague steering on the motorway, which also makes them more sensitive for crosswinds. Used this primary 4 almost 2 year. Strongly recommend purchase primary 4 plus is much better than primary 4. Just installed three months primary 4 plus in my other family car Elantra .so far so good

They are expensive, but at least they last for a very long mileage. They offer good grip in any road condition, as long as it is not snow/ice. I use them as winter tires because seeing snow where I live is rare, and they perform decent in the cold (-5ºC/-10ºC aprox). In my case I drive them up to 205km/h (autobahn) no problem, my car does not go much faster. You can definetly push them around corners, but they wont give good feedback. Good wet handling, and very easy to recover after aquaplaning at highway speeds. Nice confort and quiet ride, would recommend for people looking for a nice tire to do fast driving without getting in too much trouble. Definetly changing them for some pilot sport 5 or simmilar.

Great tire for comfort and ride but complete rubbish for wear - I got less than 25,000km out of a set and will not go there again at the price Rubbish Michelin

I have driven these tires for 47k miles in just over two years and they are still legal (just). I will be replacing them soon with the same, as they have proved to be the best tires I have ever driven on all my cars. They got slightly noisier with wear, but overall much quieter than other tires I had on the same vehicle. The roads in the UK can have quite rough surfaces, but the road noise is better with these tires than in all the others I had. The handling is excellent for my needs, as I don't drive the car harshly, but when I needed to break, pull at a round-about, or to make an evasive maneuver, it never let me down. The levels of comfort are also very good, having driven 1,400 miles in two consecutive days across Europe feeling like in a limo.
