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 Rocky's Tire & Service, this street-legal track tire is a smart fit for enthusiasts who value repeatable lap behavior over everyday commuting comfort.
Built around 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. As tread depth decreases, dry traction improves, while wet-road use becomes more limited—especially when shaved or worn.
The active catalog includes a focused range of passenger SL sizes, including 205/60-13, 205/50-15, 225/45-15, 225/50-16, and 235/40-17. If you are building a track-day or autocross setup, Rocky's Tire & Service can help you compare fitments and plan your next event tire purchase.
