The Toyo Proxes R888R builds on the race-proven Proxes R888 with a larger contact patch for quicker lap times and stronger dry handling. It gives predictable response even at big slip angles. It is a DOT competition tire meant for track and competition use, and it should not be driven in consistently cold weather.
