Newly released for the 2026 season, the Bridgestone Potenza RE-71RZ is the highly anticipated successor to the championship-winning RE-71RS. Aimed squarely at autocross, time attack, and grassroots racing enthusiasts, the RE-71RZ represents a significant leap in raw mechanical grip and thermal stability. In head-to-head testing at Japan's Tsukuba Circuit, it shaved nearly 0.75 seconds off the lap times of its predecessor in both dry and wet conditions. Whether you are hunting for a podium in the SCCA Solo series or pushing your limits at Canadian Tire Motorsport Park, the RE-71RZ is engineered to keep you at the "pointy end" of the competition.
ENLITEN™ Technology Suite: Bridgestone’s latest design approach that utilizes sustainable materials and lightweight construction to reduce rolling resistance and improve heat management without sacrificing peak traction.
NanoPro-Tech™ High-Grip Compound: A specialized molecular-level rubber blend that optimizes the interaction between silica and polymers, providing a significant leap in "stick" on both dry and damp track surfaces.
ULTIMAT EYE™ Contact Patch: Developed using advanced digital modeling to ensure a more uniform pressure distribution across the tread, resulting in higher lateral grip and more predictable handling during high-G cornering.
Reconfigured Asymmetric Tread: Features a larger, stiffer outside shoulder than the RE-71RS for immediate steering response, combined with a strategic inside-edge main groove to suppress uneven wear.
Rapid Warm-Up Design: Engineered for almost instantaneous thermal activation, ensuring you have maximum grip from the very first corner of a session or autocross run.
Season: Extreme Performance Summer
Tire Type: Street-Legal Track & Competition (200 TW)
Vehicle Compatibility: Track-focused builds (e.g., Porsche 911, Corvette, GR86/BRZ, Civic Type R, Miata)
Available Sizes: 45+ sizes ranging from 15" to 20" wheel diameters
UTQG: 200-A-A
Warranty: Bridgestone Gold Pledge Limited Warranty (Note: As a competition-focused tire, it does not carry a mileage treadwear warranty).
Tire pricing and availability vary based on specific size requirements (width, aspect ratio, and rim diameter). Sparky X provides professional mobile installation throughout the Greater Toronto Area, Durham, and York Region—we bring the tire shop to you.
