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 quick lap times. At Discount Tire & Automotive Inc., this specialty model is a smart fit for enthusiasts who value repeatable track performance over everyday commuting comfort.

Built around an R-compound tread formulation and a stepped tread pattern, the Proxes RA1 is designed to handle repeated heat cycles while supporting strong cornering response and acceleration. New tread depth starts at 8/32", and shaving is part of the performance story: dry traction improves as tread depth is reduced, with Toyo noting better dry performance around 6/32" and more track-focused behavior as the tire wears further.

Because wet traction is limited compared with normal street tires, especially when shaved or worn, this tire should be used with caution in rain and never in standing water. It is also not intended for cold-weather driving. Shop approved sizes like 205/60-13, 235/40-17, and 255/40-17 to find the right RA1 fit for your build, or browse more Toyo options on the Toyo tire brand page.
