“Had a shop install two new Michelin Primacy 4 in the front of my W124 yesterday. On the way back home i checked the pressure and the right one was a little on the low side. Drove the car today and after a few kms of city driving i noticed it was steering itself to the right once i was out of the stop and go traffic. Got out of the car and the tire was almost flat. I put 2.7 bar in it at the first station but noticed the sidewall is now damaged and there's a buldge... How is this possible? It is wet and i can hear the sound of air coming out of the tire but can't identify where it comes from. If the rim is the problem, why did they install the tire without noticing me first? If they don't admit their fault and blame it on the rim, i'm going to have to buy a new tire...”

Positive
Michelin Primacy 4
Community sentiment towards the Michelin Primacy 4 is generally positive, with drivers frequently praising its quiet ride, comfort, and dependable wet and dry braking performance. Several owners note impressive longevity reaching over 50,000 to 70,000 km, though some EV and SUV drivers report accelerated wear and fragile sidewalls over rough terrain.

“I might try to have a look at one today. There are two Uniroyal shops near me. Whether they have one in stock to look at though...? The trouble is they look really nice online but I'd like to see them in the flesh first. The old tyres (above photo) that were on these wheels were that nice square edged profile that I like, much the same as the Michelin Pilot Sports. These are going on my sons Golf EV so I'm also trying to consider if they are A rated for fuel, the best wet grip I can find and the lowest decibel level. The best choice I can find is the Michelin Primacy 4 which are A, A and 68. But on Black Circles it says they were designed for BMW. I'm sure they fit any wheel but do those properties still hold? I've always bought Pilots but B, B and 72, and its this 72 that really bugs me, is whats making me invest so much time into getting the right tyre for Toms EV. I'm getting a Tesla this Tuesday which does in fact come with the Pilots so they must be good on EV's anyway. Who knew buying tyres was so complicated.”

“Am avut primacy 4 pe o electrica. Destul de dezamagit de faptul ca dupa ~ 28.000 km s-au tocit rau de au ajuns cam la 3 mm. Placute la condus, silentioase, dar nu cele mai aderente. Pilot sport 4 pe aceiasi electrica cu primacy 4. Huruie de te doare capul. Aderenta nu o simt neaparat wow fata de primacy 4. Nu le mai suport si abia astept sa le trec pe iarna, oricum asta fiind ultima incaltare cu ele. Pe o termica am primacy 5, si sunt cele mai ok din experienta mea. Cele mai silentioase si aderente din cele 3. Dupa 20.000 km uzura a scazut cam cu 1 mm. Recomandarea mea e sa alegi primacy 5 fara ezitare.”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
