“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).

“Michelin Primacy 4 in Snow Alright, I have some pretty fresh Primacy 4 tires that came on my 2022. I live in Minnesota and don't commute much in winter but do make some shorter trips in a metro area. What is the likelihood that I'm going to want/need different tires for winter? I thought about getting a set of Crossclimate tires and just using them year round but it seems like such a waste to not use up these nice Primacy 4 tires. It probably won't be very cost effective to un-mount and mount every year. Let me have it. Read more”

“Am at Saifees, Mumbai. One of my Primacy 4 got punctured at an angle, so is wasted. The tread depth on these 4 year old, 41350 km run is just less than 4mm, so due for replacement after another 5-10k (3mm depth). Saifee tells me Primacy 5 may come at year end. Some tyres willl be manufactured in India (unconfirmed, but usually Saifee knows better) , but can't predict which ones. Meanwhile I've taken an Apollo Alnac in very good condition for Rs.1500/- and will change all tyres together to Primacy 5.”

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.
