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 Gunnell's Tire & Service Center, 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 setup when dry traction is the priority. Toyo also notes that wet traction is better when new, while shaved or worn tires should not be driven in wet conditions, especially standing water.

Available in select enthusiast sizes like 205/60-13, 225/50-16, and 235/40-17, the RA1 is built for drivers who want a focused competition tire rather than a daily-driver all-season option. For help choosing the right fitment or planning your next track setup, Gunnell's Tire & Service Center can help.
