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 Lisac's Tire, this street-legal track tire is a smart fit for enthusiasts who value repeatable lap behavior over everyday commuting comfort.

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

If you’re shopping for a track-day or autocross setup, the RA1 is available in select enthusiast sizes such as 205/60-13, 225/50-16, and 235/40-17. For help choosing the right fitment or planning a competition-ready setup, contact Lisac's Tire or start with Shop Tires.
