How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
