Tire Compound

The rubber formulation determining grip versus longevity. Street tires (200+ treadwear) last 30,000+ miles. Extreme performance street tires like Yokohama Advan AD08 (180 TW), Bridgestone RE71RS (200 TW), and Toyo R888R (100 TW) trade longevity for grip. Track-only slicks have no treadwear rating. Lower treadwear = more grip and faster wear.
