                                             Proxes RA-1 Competition Radial shown above.

Proxes RA1 Competition Radial Specs.:

• High-grip tread compound dispersed in Solution SBR compound for enhanced grip in both wet and dry, plus uniform wear.
• Nylon cap and edge plies to maintain optimum footprint shape and grip at high speeds.
• Two-ply rayon casing construction for thermal stability at high speeds and sidewall rigidity when cornering.
• Base compound to resist heat at high speeds.
• Special sidewall compound to protect casing plies and provide heat resistance at high speeds.
• Free floating steel cord side ply for sidewall rigidity, cornering stability, and steering response.
• DOT Approved.
• Treadwear:100
• Traction:AA
• Temperature:A
• Operating temperature:160 degrees to 220 degrees.
• Target Hot Inflation Pressure:High 30's to Low 40's(PSI).
• Recommended Camber:-2.0 Degrees to -5.0 Degrees.
• Maximizing Tire Life:The degree of negative camber required to get the most performance out of the RA1 can often lead to inside shoulder wear.  To maximize tire life, the tire should be dismounted from the wheel and flipped, move inside shoulder to the outside, when the tire is about half way worn.
• Directional Tread:The directional nature of the RA1 tread pattern is only applicable for wet conditions to optimize water drainage.  If they are being used in dry conditions, the direction of rotation does not matter.
• Tread Depth:At its full tread depth of 8/32 inch, the RA1 provides excellent wet traction.  For excellent dry traction, and tread wear, we recommend shaving the RA1 to 4/32 inch.  So, we recommend having on hand, a set of non-shaved RA1's as "rain tires", and a set of shaved RA1's as "dry tires".
