The Toyo Proxes R888R is an extreme-performance, semi-slick tire developed as the successor to the race-proven Proxes R888, engineered for faster lap times and stronger dry-weather grip on track days and autocross while remaining street legal. It uses a high-grip race compound and an optimized tread pattern with a wide center rib and large outer tread blocks to maximize contact patch and cornering stability.

Fitment: A 285/35 ZR19 (99Y) sizing widely used on high-performance platforms such as the BMW M3 and M4 (E92, F80, G80) and Toyota Supra (A90); as with any tire, fitment is governed by the vehicle's wheel and tire size rather than a specific make/model lock-in.
