Winner: Pirelli Scorpion All Terrain Plus — better handling, noise and treadwear. It leads or ties in every category we score.
Pirelli Scorpion All Terrain Plus scores 92 vs 84 on handling.
Pirelli Scorpion All Terrain Plus scores 86 vs 82 on noise.
Pirelli Scorpion All Terrain Plus scores 91 vs 87 on treadwear.
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.
