Engine & Performance Warehouse R888 Toyo Proxes R888R DOT Competition Tire

The Toyo Proxes R888R is a DOT-legal competition tire engineered for drivers who demand maximum performance on the track. An evolution of the race-proven Proxes R888, the R888R delivers even faster lap times and superior dry handling through an improved contact patch and advanced R-compound tread formulation.

Key Features:

• High-Grip Race Compound – Reaches optimal operating temperature quickly for consistent lap-to-lap performance
• Optimized Contact Patch – Puts more rubber on the track to improve dry traction in braking, acceleration, and cornering
• Asymmetric Tread Design – Large outboard shoulder blocks maximize lateral grip; enables cross-rotation to reduce irregular wear and extend tread life
• Wide Center Rib – Improves directional stability and delivers precise, responsive steering feel
• Water Evacuation Channel – Assists wet-weather traction by moving water away from the contact patch
• Two- or Three-Ply Rayon Casing – Paired with two wide high-tensile steel belts and a spirally wound nylon-reinforced ply for high-speed stability and durability
• UTQG 100 – Tread depth of 6.3/32" from the factory
• Available in 13" through 20" rim diameters – Wide size range covering popular performance and track-day fitments

The Proxes R888R is ideal for road racing, time attack, HPDE events, NASA and SCCA competition classes, and autocross. The soft, sticky R-compound tread delivers relentless grip in dry conditions; however, the tire should not be used in sustained temperatures below 45°F or in standing water, snow, or ice. Recommended hot inflation pressure is 32–38 PSI, with an optimal operating temperature range of 160°F to 220°F.
