Toyo Proxes RA1 Tires

Product Info

Proxes RA1

The Toyo Proxes RA1 tires are a DOT-marked competition option for racetrack and autocross drivers who want consistent grip, durable construction, and a cost-conscious path to quicker lap times. At American Tire Depot, this street-legal track tire is a strong fit for enthusiasts who prioritize repeatable lap behavior over everyday commuting comfort.

Built around an R-compound tread formulation and a stepped tread design, the Proxes RA1 is designed 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 in standing water and cold conditions.

Available sizes include 205/60-13, 235/40-17, and 255/40-17, with additional fitments across classic enthusiast wheel diameters. If you are building a track-day or autocross setup, American Tire Depot can help you compare options and schedule service with confidence.
