The TOYO Proxes RA1 is a DOT competition tire developed from race-proven design and component technology. Built for road racing and high-performance driving, this radial tire delivers quick lap times, consistent handling, and long wear. Its full 8/32-inch tread depth provides dependable competitive wet traction, while shaving the tread to 4/32-inch can enhance dry-track performance. The 255/50ZR16 fitment, 95 load index, and Z speed rating make it a focused choice for drivers seeking responsive performance from a dedicated competition tire.

• Stepped tread design increases the contact area and limits tread void for improved dry traction, while the groove arrangement supports wet-weather grip.


• Directional tread design uses staggered tread blocks to maximize traction and handling while helping reduce road noise for improved ride comfort.


• Soft yet durable R-Compound rubber enhances grip for competitive cornering, acceleration, and braking performance.


• Tubeless radial construction supports stable handling and predictable response during demanding track use.

The TOYO Proxes RA1 features a black raised-letter sidewall and a performance-oriented tread engineered for drivers who prioritize control and consistency. The directional pattern helps maintain confident contact through corners, while the durable R-Compound balances traction with extended service life compared with softer, less durable competition compounds. As a DOT competition tire, it is designed for racing and high-performance applications rather than general-purpose touring use. Professional installation, proper balancing, and alignment are recommended before use, along with regular inspection of tread condition and inflation pressure.
