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 consistent grip, durable construction, and a cost-conscious path to quicker lap times. Big Brand Tire & Service can help you choose this street-legal track tire for builds that prioritize repeatable performance over everyday commuting comfort.

Built around an R-compound tread formulation and 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 setup, with dry traction improving as tread depth is reduced. Wet-road use becomes more limited as the tire wears, so caution is important in rain and standing water.

Available in enthusiast-friendly sizes like 205/60-13, 235/40-17, and 255/40-17, the Proxes RA1 fits a wide range of track-focused projects. If you are planning a motorsport setup, Big Brand Tire & Service can help you compare options and schedule your next appointment.
