Product Info

Proxes RR

Toyo Proxes RR tires are built for drivers who want a DOT-compliant competition tire for road racing and autocross in dry conditions. At American Tire Depot, this purpose-built option is a strong fit for enthusiasts who prioritize traction, steering response, and lap-time consistency over everyday street use.

The Proxes RR uses an enhanced-grip tread compound with a semi-slick pattern, two 4/32-inch circumferential grooves, and wear inspection holes in the slick regions. It is designed to be ready to race without shaving, and Toyo recommends heat cycling before competition to help improve wear and performance consistency. Reinforced sidewalls and symmetric construction support cornering stability, while the sidewall marking area helps racers manage tire sets.

This tire is intended for dry-track use only and should not be driven in wet conditions, standing water, or temperatures near freezing. If you’re building a track-day setup, American Tire Depot can help you compare approved sizes like 205/50-15, 235/40-17, and 295/30-18, along with the rest of the Proxes RR lineup. For setup planning, Toyo also publishes guidance on camber, hot pressures, and operating temperature.
