Toyo Proxes RA1 Tires

Product Info

Proxes RA1

The Toyo Proxes RA1 tires are a DOT-marked competition choice for racetrack and autocross drivers who want consistent grip, durable construction, and a cost-conscious path to quicker lap times. At Advantage Tire Pros, this street-legal track tire is a smart fit for enthusiasts who value repeatable performance over everyday commuting comfort.

Built with an R-compound tread material and a regular 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 setup when dry traction is the priority. Toyo notes that dry traction improves as tread depth is reduced, while wet use becomes more limited as the tire wears.

Available in select enthusiast sizes like 205/60-13 and 235/40-17, the RA1 is best matched to track days, autocross, and other closed-course events. For fitment help or setup questions, Advantage Tire Pros can help you choose the right size and plan your next appointment.
