Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip and treadwear start at “Important” — the two things buyers rank highest. Move the sliders and the scores update instantly.
Neither tire has a score here yet, so this weight changes nothing.

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.
