Toyo Proxes RA1 Tires

Product Info

Proxes RA1

The Toyo Proxes RA1 tires are a DOT-marked, street-legal competition choice for racetrack and autocross drivers who want consistent grip, durable performance, and a cost-conscious path to quicker lap times. Trendsetters Truck & Auto can help shoppers choose this specialty tire for track-focused builds that prioritize repeatable lap times over everyday commuting comfort.

Built around an R-compound tread formulation and a 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 performance story: dry traction improves as tread depth is reduced, while wet traction becomes more limited on shaved or worn tires. Toyo also notes that these tires should not be driven in wet conditions, especially standing water, or near freezing temperatures.

Available fitments include enthusiast sizes such as 205/60-13, 235/40-17, and 255/40-17, with a size range that suits classic and lightweight performance applications. For help narrowing down the right setup, Trendsetters Truck & Auto also offers Tire Consultation and Schedule Appointment.
