Toyo Proxes RA1 Tires

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. Automotive Outfitters can help track-focused shoppers find this street-legal circuit tire for builds that 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 designed 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 setup: dry traction improves as tread depth is reduced, while wet traction is best when the tire is new. Toyo warns against wet use when shaved or worn, especially in standing water.

Available in a focused set of enthusiast sizes, the RA1 fits a range of older sports cars and autocross builds. Shop approved sizes like 205/60-13, 225/45-15, and 235/40-17, or browse more options from Toyo. For track-day setup support, consider Schedule Appointment with Automotive Outfitters.
