Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

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.
“Yokohama es la que va pero fijate que ya este año salieron las nuevas advan v61, esas geolandar g058 son modelo viejo. Las primacy 4 son modelo viejo y te las cobran como si fuesen oro. Bridgestone y continental tambien las vi a precio de oro. Pirelli son medio pelo, no son malas pero son ruidosas, ya que estás en el baile podes ir por algo mejor, como las yokohama.”
“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”
“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”

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.
