Evolving and coming from the Proxes R888, the Proxes R888R is Toyo’s Racetrack & Autocross Only tire designed for driving enthusiasts participating in track days, road racing and high-performance driver education events. These tires are not intended to be driven in near-freezing temperatures. The Proxes R888R feature a special R-compound tread that quickly reaches operating temperature and provides high grip levels for maximum cornering traction. The tread compound is molded into an aggressive, asymmetric tread pattern with massive outboard shoulder blocks to provide lateral grip needed when driving on the track. Continual development of the contact patch gives the Proxes R888R greater levels of dry traction for improved braking, acceleration and cornering versus it’s predecessor.
