I bought these tyres in May 2019. If I remember correctly, Michelin advertised them to last 20,000 miles. At the moment of writing, November 2021, I have driven 21,000 miles with them and have less than 2 mm tread left on all 4 tires. Right now, I can feel they are at the end of their life. :D The performance of the tires was really good on both dry and wet surfaces. I used them mostly on UK's roads, but also took a trip around Europe with them for around 5,000 miles.

Pros: Wear - I have this tyres for 30,000km before having to replace them due to puncture. I reckon they can go at least another 10-20k km more. Driving style is 70% highway and 30% city. Comfort - Tyres soak up imperfections on the road well and are relatively quiet. It start to get noisier at around 20,000km Cons: Wished the aquaplaning resistance is better especially when there is water pooled at the side of the road. Anything faster than ~80km/hr and you will feel it. Struggle for traction especially when the road is wet and you need to exit a slip road slightly faster. Overall: Good comfortable tyres for those who drives leisurely. If you want some dynamic better to explore other tyres in the market

Excellent tire for a compact SUV and other smaller vehicles. Exceptional handling on occasional wet roads in summer. Dry surface, absolutely no complaint there. Great looking tires, quiet as well. Awesome traction for braking. My go-to tire for replacement in the future.

So I'm not comparing these to sports tyres, but to eco touring tyres. The Primacy 4's feel really sticky. Not slippery at all. The grip is great, also in the corner. Compared to regular touring tyres this feels almost like a performance tyre. It’s a premium touring three season tyre that has fantastic grip. The supposed side wall deflection I sometimes read about is really, really not an issue for me. The steering feels a bit heavier, but in a good way. It for sure feels very secure in curvy mountain roads and curvy asphalt down hills. Much more secure in faster turning. I feel like I'm glued to the road going up to our house over curvy steep mountain roads here in Japan. My car does have a relatively low centre of gravity with a (underpowered) boxer engine. I feel the Primacy 4's are good to use till 5C. You'll not be as secure as in spring, the rubber compound will get a bit harder, but still usable.

OK, these tires are good, really. I had the Primacy 3, Dunlop blue response, these and the Primacy 4* (BMW motorsport edition OEM), on the same car. The primacy 4 are overall, the best, being comfortable, safe and quiet. They are not sports tires, but you can push them and they won't let you down, on dry or wet. They are good for highway as well as for cornering, this is what you can call a very well balanced tire. The wear is good also and you won't feel like it loses quality as it wears. Now to make a comparison with the primacy 4*(bmw motorsport edition)... i would say the normal Primacy 4 is more balanced, is good for long drives, especially. The 4*, otoh, has more grip, more control but for long rides is not so much fun, will get you tired, faster, being more noisy, less comfortable. The 4* is a true sprots tire, unlike Dunlop Blue Sport Response, which is sports just in name...so if you wanna have fun and commute, go for the 4*, if you wanna drive relaxed and safe, then get the normal primacy 4. The 4* is very precise, feels like glued to the ground, by comparison, you feel a bit like on a track with it. Also acceleration and braking is a lot more efficient and faster, while losing on comfort a little.... i love the the 4* in every situation, except on very long rides. It's basically a Primacy 4 on steroids with super glue on it.. awesome engineering there. The wear is just as good on 4 or 4*, they seem both to have good wear, about the same. Probably on a good sound insulated and heavier car, the 4* is the better choice even for long runs, so you gotta try that. Price is about the same, you have ask the dealer to bring you some as those you can't easily find in stock.

Having switched from Continental Premium Contact 5, I could immediately feel a disconcerting vagueness in the steering and handling of the car. It instantly feels less connected to the road. Floaty and even that 'slippery' feel. It could well be due to that the specially-formulated compound that is to give Primacy 4 its low wear and rolling resistance properties. But it does not inspire as much confidence as the CPC tyres I have been using for the last 15 years or so. So much so I have made a mental note to exercise greater caution when driving in the torrential rain. However the Primacy 4 rewards abundantly in competently smoothing out the unevenness in the roads and offering a quiet cabin for a most comfortable drive.

Excellent dry grip and decent wet grip. Being a comfort based tyre, the sidewalls do feel a bit mushy. It’s quiet and returns good mileage. However, I probably would not buy them again as they are expensive. Other brands like Goodyear or Dunlop have tyres that perform just as well and are priced more fairly.

I HAD TWO MICHELIN TYRES PUT ON THE FRONT (LONG STORY )ONE WAS MICHELIN PRIMACY 3 THE OTHER MITCHELIN PRIMACY 4 AND FOUND THAT THEIR LONGLIVITY WAS IDENTICAL ON NORMAL ROAD USE -

I used to have Rub Flats on my little 2 seater - the ride was horrendous and jarred over every bump and crashed and skittled over all over the place. Having read reviews of the tyre and how bad they were I decided to get some new ones - specifically the non run flats that were geared for comfort. The Primacy 4s are outstanding! The difference in my car with regards to the comfort is on another planet. I no longer feel or hear the crashing over the slightest bumps or creases in the road - these are amazing. I can go around corners with scared road surfaces with ease without skittling over to the other side of the road. I love these tyres. It was suggested to me I should go for the sportier Michelin Sport 4's as they are superb handling and performance tyres. Well I'm sure they are but for me - I was concerned about enjoying the drive rather than being able to go round corners at break neck speed. Having said that I've taken my little 2 seater up and around the mores in Saddleworth and drove spiritedly and these were perfect! Gripped when I needed them.

My Audi Avant S-Line was mounted with Bridgestone Potenza 245/40 R18 and was uncomfortable riding around town. However, since its replacement with Michelin Primacy 4, the car became so comfortable. The ride is so soft now. I love these tires.

Excellent tires, they handling well in dry and wet , very good road feedback, in my city it's snow for a one week i tried them in snow it works, know primacy 4 is summer tiers but they actually work a little slippery but works. No problems at all.

Excellent dry grip but not so confident in the wet. aquaplaning can be a problem too
