Toyo Proxes RA1 Tires

Product Info

Proxes RA1

The Toyo Proxes RA1 tires are a DOT-marked, street-legal competition option for racetrack and autocross drivers who want consistent grip, durable performance, and a cost-conscious path to quicker lap times. Tire World, Inc. can help track-focused shoppers choose this specialty tire for builds that value repeatable lap behavior over everyday commuting comfort.

Built around an R-compound tread formulation and a stepped tread design, the Proxes RA1 is intended to handle repeated heat cycles while supporting responsive cornering and strong acceleration. New tread depth starts at 8/32", and shaving is part of the performance setup, with dry traction improving as tread depth is reduced. Wet-road use becomes more limited as the tire wears, so caution is important if conditions are damp or standing water is present.

Available fitments include enthusiast-friendly sizes such as 205/60-13, 235/40-17, and 255/40-17. If you are building a club-racing or autocross setup, browse more Toyo options at Toyo tires or start with Shop Tires at Tire World, Inc..
