A unique semi-slick shoulder area, continuous center contact, and enhanced R compound combined with the V-shaped tread design make the R888 ideal for road racing, track days, and high-performance driving schools. In competition, the improvements in casing and tread design increase dry performance, while maintaining wet traction and control. The R888 provides consistent performance throughout the life of the tread.
General Proxes R888 setup guidelines:
Operating Temperature: 140°F to 220°F, optimum around 200°F
Hot Inflation Pressures: High 30s to Low 40s (psi)
Camber: -2.5° to -5.0°
Caster: As much positive as possible

Features and Benefits Competitive Handling and Improved Performance
Advanced casing and V-shaped tread design
Stiffer construction and wider tread width enable the R888 to generate more cornering force, with less heat degradation
Spiral wound cap ply (construction may vary by size)
Steering Response
Semi-slick shoulder area improves steering response
Steel wire reinforced sidewalls (construction may vary by size)
Braking Performance and Dry Traction
Continuous center contact increases braking performance and feel when compared to the Proxes RA1.
Tread depth can be shaved to maximize dry traction
Wet Traction and Control
The V-shaped tread design also enhances wet traction and control
