    No owner ratings of noise for Primacy 4 or Primacy 4 ST. The owner half is the owners’ average (67): owners’ noise ratings barely follow the road tests, so the tests say nothing about how owners would rate it.

Tire A

Michelin Primacy 4

Positive

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. It is commonly viewed as a premium touring tire that commands high prices compared to competitors.

“I'll have to remember to get some E's. That aside, the primacy 4 fitted to the mokka only have 6.5 mm, if that, from new so perhaps they were just an older name. Gaz”

“Both our Polestar2 (new) and 2016 Leaf (Jap import) arrived with Primacy 4s on them. The FWD Polestar needed fronts replaced at ~35k km and being 245/45 R19s Primacy were too pricey so went with Kumho Ecsta PS71 equivalents for a lot cheaper and negligible difference in performance. The rears on the Polestar are still going strong at 45k km and look like at least 60k km will be likely. We also fitted Kumhos on our previous Leaf and were very satisfied with performance and life.”

“Review Michelin Primacy 4 — impresii după 2 sezoane de utilizare Salut comunitate! 👋 Vreau să împărtășesc experiența mea cu anvelopele Michelin Primacy 4, pe care le folosesc de aproximativ 2 ani pe mașina de familie (un VW Golf 7). De ce am ales Michelin Primacy 4: Am citit multe teste comparative și Primacy 4 ieșea constant în top la frânare pe ud Garanția de 4 ani la uzură Pretul era ok pentru ce oferă (le-am luat de pe avemanvelope.ro la vremea aia) Experiența după 2 sezoane: ✅ Ce mi-a plăcut: Frânare excelentă pe ploaie — diferența față de anvelopele chinezești pe care le aveam înainte e uriașă Zgomot redus — nu se aude aproape nimic la viteze de autostradă Uzură uniformă — am 35.000 km pe ele și mai au cam 4-5mm profil Consum combustibil similar cu ce aveam înainte (nu am observat impact) ❌ Ce nu mi-a plăcut: Prețul — sunt cu ~30% mai scumpe decât alte brand-uri premium Pe zăpadă nu sunt extraordinare (dar sunt anvelope de vară, ce să mai) Verdict: Dacă bugetul permite, le recomand cu încredere. Pentru mine, siguranța la frânare pe ud a fost factorul decisiv. Le-aș cumpăra din nou. Pentru cine e interesat, le găsiți aici: Voi ce anvelope folosiți? Ați avut experiențe bune cu Michelin sau preferați alte brand-uri? Read more”

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.

Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
