Toyo Proxes R1R



The Proxes R1R is extreme performance for serious street driving in sports coupes and sedans.
Developed from years of grueling on-track experience and engineered to elevated performance standards, it allows capabilities beyond normal driving limitations. An aggressive, arrowhead tread design, extra wide footprint, high-grip compound, and advanced autocross-inspired casing design, provide every advantage while driving hard through the corners and quickly accelerating in the straight-aways.

Proxes R1R Tech Specs:
  • Silica-Reinforced, High-Grip Tread Compound Improves grip for better handling and performance during high-spirited driving.

  • Unidirectional Arrowhead Tread Design Shallow grooves and a unidirectional pattern achieve balanced performance between wet and dry conditions.

  • Tapered Center Block Edge Stabilizes center block movement to decrease irregular wear. Helps to increase hydroplaning resistance.

  • Multi-Width EVAC Channels Improve water evacuation. Narrow width at the tire edge widens the shoulder block area to enhance steering.

  • Stability Control Slits Provide resistance to irregular wear. Improve dry performance by maintaining block stiffness during aggressive braking.

  • Advanced Autocross-Inspired Casing With Modified Radial Construction Improves steering response and handling by optimizing the contact patch shape.
