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. At Ron Gordon’s Tire Pros, this specialty model is a strong match for enthusiasts who prioritize repeatable track 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 story: dry traction improves as tread depth is reduced, while wet traction becomes more limited on shaved or worn tires.

Available sizes include 205/60-13, 225/45-15, 235/40-17, and 255/40-17. If you’re comparing DOT competition tires or planning a track-day setup, Ron Gordon’s Tire Pros can help you choose the right fit and schedule service with confidence.
