Bridgestone 008839 Potenza S007 RFT 245/35ZR20 91Y Run-Flat Max Performance Summer Tire

The Bridgestone Potenza S007 RFT is a Max Performance Summer run-flat tire engineered for ultra-high-performance sports cars and high-speed vehicles. Originally developed as original equipment for the 2013 Ferrari F12berlinetta, the S007 RFT delivers motorsport-derived performance technology in a self-supporting run-flat construction.

Bridgestone engineers drew on 14 seasons as the official FIA Formula One tire supplier, combining advanced construction techniques with molecular-level compound optimization — blending carbon, silica, and rubber to maximize grip while reducing rolling resistance and fuel consumption.

Run-Flat Technology:

• Self-supporting run-flat construction allows continued driving up to 50 miles at 50 mph after complete air pressure loss
• Reinforced sidewall structure supports vehicle weight even after a puncture
• Recommended only for vehicles originally equipped with run-flat tires and a tire pressure monitoring system (TPMS)

Tread Design & Performance:

• Asymmetric tread design with wide outside shoulders and unyielding notched ribs for superior dry-surface steering response and grip
• Wide circumferential grooves channel water away from the contact patch to maintain wet traction and resist hydroplaning
• Rigid tread pattern blocks deliver maximum cornering grip even under severe lateral load conditions

Internal Construction:

• Twin steel belts reinforced with two layers of spirally wrapped nylon for high-speed durability and high-g cornering stability
• Rayon cord casing with specially tuned construction optimizes cornering grip under extreme loads
• Specifically formulated silica compound reduces rolling resistance and contributes to improved fuel efficiency

Important: As a summer tire, the Potenza S007 RFT is not intended for use in near-freezing temperatures, snow, or icy conditions. Comes backed by Bridgestone's 5-year manufacturer's warranty.
