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 255/40R17 size is rated 98W for load and speed with extra load (XL) construction. It offers 6/32-inch tread depth, a 50 psi maximum inflation pressure, a UTQG rating of 100AAA and an overall diameter of about 25 inches.
