Bridgestone Battlax Racing Street RS12 — 200/55ZR17 Rear

The Battlax Racing Street RS12 is Bridgestone's newest flagship street-legal sport tire, launched for the 2026 model year as the direct replacement for the RS11. It was developed using technology and data from Bridgestone's FIM Endurance World Championship race program under the concept "From Circuit to Street." The front tire introduces the HE-MS Belt (High Elongation Mono-Spiral Belt), a construction used for the first time on any production Battlax street tire, paired with a newly designed tread pattern with an optimized groove ratio and a race-derived compound. Bridgestone states the RS12 cuts lap times versus the RS11 and holds high grip more consistently over repeated track sessions.

• HE-MS Belt front construction (first use on a production Battlax street tire)
• New race-derived compound for higher dry grip
• New tread pattern with optimized groove ratio
• Developed using Bridgestone's Endurance World Championship racing data
