The Proxes R888 is Toyo's Racetrack & Autocross Only tire for driving enthusiasts participating in road racing, track days and high-performance driving schools. The Proxes R888's advancements in casing and tread design improve dry performance while maintaining wet traction and control.While Proxes R888 radials meet DOT requirements, they are not recommended for driving in wet conditions when shaved or worn where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. And like all Racetrack & Autocross Only tires, Proxes R888 radials are not intended to be driven in near-freezing temperatures, through snow or on ice. It's also essential these tires be stored indoors at temperatures maintained above 15 degrees F. Proxes R888 tires feature a R-Compound Tread that maximizes grip for better competitive handling and performance. This compound is molded into a directional V-shaped tread design featuring increased tread area and limited void to improve dry traction while the V-shaped grooves assist with wet traction. Semi-slick shoulder areas improve grip for better steering response while a continuous center contact increases braking performance and dry traction.The tire's internal structure features an advanced competition modified radial construction for driving hard through the corners and accelerating quickly onto the straight-aways.Toyo Tires recommends the following general set-up guidelines for the Proxes R888:Operating Temperature: 160°F to 220°FHot Inflation Pressures: 32 to 38 (psi)Camber: -1° to -3°Caster: As much positive as possible Related Information: Competition Tire Heat Cycling Service | Shaving Tires for Autocross / Track Use / Competition | Recommendation on Proper Use, Handling and Storage of This Tire in Colder Climates (PDF)
