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.
The 325/30ZR20 size is rated 102Y for load and speed. It offers 6.3/32-inch tread depth, a 51 psi maximum inflation pressure, a UTQG rating of 100AAA and an overall diameter of about 27.7 inches.
