Toyo Proxes RA1 Tires

Product Info

Proxes RA1

The Toyo Proxes RA1 tires are a DOT-marked competition option for racetrack and autocross drivers who want a street-legal tire built for consistent grip, durable performance, and quick lap times. Tire Crew can help you shop this specialty model when your focus is closed-course use rather than everyday commuting.

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 strong acceleration. Toyo notes that a new tire starts at 8/32" of tread depth, with dry traction improving as the tire is shaved; wet traction is best when new, but shaved or worn tires should not be driven in wet conditions, especially standing water.

This model is a strong fit for enthusiast builds that spend more time on course than on the street, with active catalog sizes in 13-, 15-, 16-, 17-, and 18-inch passenger fitments. Available options include 205/60-13, 225/50-16, and 235/40-17. For more Toyo options, visit the Toyo tire brand page or Shop Tires.
