Secure Checkout GuaranteeEngineered for autocross, time attack, endurance racing, and HPDE enthusiasts and racers, the Proxes Sport R features a directional tread pattern, reinforced casing, and a high grip compound. Its long contact patch, large shoulder blocks, and connected center rib maximize ground contact and stability—delivering improved control, consistency, and quicker lap times.
Wet Braking
Rated A for wet traction, an above-average grade. That means shorter, more predictable stops on wet asphalt.
High-Speed Stability
Certified to 168 mph (W rating), with top-grade heat resistance for long runs at speed.
Extra Load Strength
An XL-reinforced casing carries more weight than a standard tire this size. Good for heavier vehicles, a full load, or towing.
Skip the confusion around wheel offsets, bolt patterns, and tire sizes. Trust our tire and wheel fitment specialists to handle the details and deliver the perfect fit for your vehicle and driving needs.
