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 Tucker Tire, this street-legal circuit tire is a strong match 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 intended to handle repeated heat cycles while supporting responsive cornering and quick 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 traction is best when the tire is new, so caution is important as it wears.
Available in enthusiast-friendly sizes like 205/50-15, 225/50-16, 235/40-17, and 255/40-17, the RA1 fits a wide range of club-racing and autocross builds. Tucker Tire can help you choose the right size for your setup and get you ready for track days with confidence.
