Hankook 1020369 Ventus R-S4 Z232 255/40ZR17 98W XL Extreme Performance Summer Tire

The Hankook Ventus R-S4 (Z232) is an Extreme Performance Summer tire engineered for drivers of sports cars, sports coupes, and performance sedans who demand near-motorsport levels of grip. Designed as the aggressive successor to the Ventus R-S3, the R-S4 is built to excel at track events, autocross, and street driving alike.

At the heart of the R-S4's design is an aggressive directional tread pattern with an optimized tread contact rate per block. This engineering approach maintains maximum block stiffness whether traveling in a straight line at speed or pushing hard through circuit corners.

Key Features:

• Wider center block — Enhances steering response and on-center feel for precise directional control
• 2-channel main groove design — Efficiently evacuates water to reduce hydroplaning risk
• Variable groove angle technology — Maximizes contact patch performance across varied driving conditions
• High-stiffness shoulder blocks — Deliver confident lateral grip and stability during aggressive cornering
• Extreme Performance Summer compound — Formulated for maximum dry and wet grip in warm conditions
• XL (Extra Load) rating — Supports higher load demands typical of high-performance vehicles

Rated UTQG 200-AA-A, the Ventus R-S4 offers exceptional traction and temperature resistance for performance driving. With a 98W service description, this tire is speed-rated to 168 mph and carries a load index supporting up to 1,653 lbs per tire. The black sidewall finish gives it a clean, race-inspired appearance.
