The Toyo Proxes R888R is the only tire for driving enthusiasts participating in track days, road racing and high-performance driving. R888R radials are not intended to be driven in near-freezing temperatures, through snow or on ice.
R888R tires feature an R-compound tread that quickly reaches operating temperature and provides high grip levels for maximum traction. The tread compound is molded into an aggressive, asymmetric tread pattern with massive outboard shoulder blocks to provide greater lateral grip, a wide center rib for improved directional stability and improved steering response, a water evacuation channel and an optimized contact patch gives the R888R better dry traction for improved braking, acceleration and cornering versus its predecessor.
R888R radials meet D.O.T. requirements. Drivers should drive cautiously at reduced speeds if they drive in wet conditions when shaved or worn where standing water is present and there is a risk of hydroplaning. .
Internal construction of the R888R features a two-ply or three-ply Rayon casing, depending on tire size, supporting two wide, high-tensile steel belts. A spirally-wound nylon reinforcement ply provides additional high-speed stability and durability.
Toyo recommends the following general set-up guidelines for the R888R:
- Operating Temperature: 160°-220° F
- Hot Inflation Pressures: 32 to 38 PSI
