Toyo Tire U.S.A. Corp. has released the new Toyo Proxes RR, a DOT competition tire designed for dry tracks. Its symmetric design uses two circumferential grooves molded to a 4/32nd-inch tread depth with additional wear inspection holes on the void areas. This race-ready design eliminates the need for tire shaving and provides ultimate traction with superior cornering force, notes Toyo. The Proxes RR has a 40 C A tread wear rating and is available in three sizes: 205/50ZR15, 225/50ZR15 and P275/35ZR18 87LL.
