265/35/18 / 295/30/18 Tires

Real-world track tire rankings for treadwear 0–99, built from thousands of logged lap times. For every car model, each tire's three best laps are compared against the fastest tire on that same model — so tires are judged by the pace they actually deliver on equal machinery, not by spec sheets. Per-model margins are aggregated across the whole fleet, weighting well-tested car/tire combinations more heavily, and thin data is pulled toward the field average rather than rewarded. Treadwear classes keep the comparison fair: street tires, R-comps and slicks each compete in their own category.
