Michelin Primacy 4
The Michelin Primacy 4 is generally praised for its comfortable ride, low road noise, and strong braking and safety in both dry and wet conditions. While many users report excellent tread longevity across tens of thousands of kilometers, some note faster wear on heavier electric vehicles or rough surfaces. It is viewed as a premium touring tire that is unsuitable for winter conditions, prompting some drivers to weigh its high price against newer models like the Primacy 5 or cheaper alternatives.

“Gomme alternative a Primacy 4 Buongiorno, ho una Peugeot 208 del 2020 con delle Michelin Primacy 4 205/45 R 17 88 V, le ho da 4 anni, circa 20000km all’anno tranne quest’anno che non le ho sostituite con le invernali e che quindi dovrei portarle ad usura completa con il prossimo “giro” delle gomme per altri 20000km. In totale arriverò a quasi 100000km, quindi super ammortizzate e le consiglierei sempre anche per la tenuta. Visto che entro fine estate pensavo di sostituirle tutte e quattro, vorrei capire se ci fossero delle alternative un più economiche ma altrettanto valide (un cambio gomme al momento mi costa circa €650-700).

“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.”

“Michelin Primacy 4 or Conti UC6 - Virtus GT Hey, i recently got a Virtus GT with stock Apollo alnac 4g tyres - looking to upgrade them. As per ChatGPT my options are Michelin Primacy 4 and Continental UC6 - budget is not really a problem. Overall i want good grip, handling, comfort and low cabin noise. Not going for Pilot Sport 4, because don't want to compromise on comfort for performance when i am not going to push my car too much, hence PS4 is a no no. But read it somewhere that with Primacy 4, there is a noticeable difference in mileage not sure if it means going up or down. Need recommendations on what i should get! Thanks in advance”

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.
