The Potenza RE-71RS tire by Bridgestone is specifically designed for high-performance driving events, track days, and endurance-style competitions. It is meant for sports cars, performance sedans, and enthusiastic drivers who seek maximum grip and precise handling both on the street and at race-pace on the track. This tire is not suitable for use in freezing temperatures, snow, or icy conditions. The tire features a highly asymmetric pattern that is made from a special tread compound with race-developed, high-grip polymers. This compound is engineered to deliver exceptional dry grip. The optimized footprint helps manage contact pressure during intense cornering, ensuring a more even distribution of grip. By doing so, it promotes uniform wear and prevents areas of excessive heat generation. The solid circumferential ribs contribute to quick and precise steering response, especially during dynamic cornering events. The expansive outboard tread element incorporates low-angle grooves that enhance lateral stiffness, resulting in consistent and predictable cornering traction. Additionally, strategically placed circumferential grooves with beveled edges provide support to the inboard ribs during intense cornering while allowing sufficient resistance to hydroplaning. Internally, the Potenza RE-71RS tire features a sturdy construction. It has a two-ply polyester casing that enhances feedback and steering response. The twin steel belts provide a lightweight yet durable foundation for the tread, while a nylon reinforcement ply ensures high-speed capability. Please be aware that if the Potenza RE-71RS tires are exposed to temperatures of 20 degrees F (-7 degrees C) or lower, they need to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before any adjustments, such as inflation pressure changes or mounting on wheels, are made.
