Developed from years of grueling on-track experience and engineered to elevated performance standards, the Proxes R1R allows capabilities beyond normal driving limitations. An aggressive, arrowhead tread design; extra wide footprint; high-grip compound; and autocross-inspired casing design let you drive hard through the corners and quickly accelerate in the straightaways.
Designed to help full-sized pickups work hard on pavement, then work just as hard when roads are muddy, snowy, and rocky—or when there are no roads at all. The Open Country M/T combines solid on-road performance with extra ground clearance, higher load-carrying capacity, and greater ability to go off-road. Truck enthusiasts know it for its long wear, low noise and aggressive tread pattern.
The Proxes 1, the flagship of the legendary Proxes line, uses our most advanced technology. The result: a maximum high-speed performance summer tire, with a focus on cornering and braking, for the world’s most powerful cars.
