Toyo Tires 255500 Proxes R DOT Competition Summer Tire 245/40ZR15 88W

The Toyo Proxes R (245/40ZR15 88W) is a DOT competition tire engineered for dry road racing and high-performance driving events (HPDE). Quicker and more predictable than its predecessor, the Proxes RR, it retains the highly regarded consistency and durability that racers have trusted while pushing performance to the next level with a newly developed tread compound and all-new construction.

Key Features:

• DOT Competition Rated: Street-legal and race-ready — approved for use in NASA, BMW CCA, PCA, and other spec racing classes
• 4/32" Tread Depth: Optimized shallow tread depth maximizes contact patch for ultimate dry grip
• High-Grip Tread Compound: Newly formulated R-compound increases grip and improves lap times
• Enlarged Contact Footprint: Increased footprint length and contact area enhances braking and cornering performance
• Symmetric Tread Pattern: Provides tread surface rigidity for consistent, responsive handling
• Reinforced Sidewall: Improves stability, steering response, and driver feedback under racing loads
• Wear Inspection Holes: Allow for easy tread depth monitoring from any position during competition use
• Summer / Dry-Weather Designed: Optimized exclusively for dry conditions — not intended for wet, snow, or ice use
