Hankook 1031619 Ventus S1 evo4 X K137A 275/45R20XL 110Y SUV Summer Performance Tire BW

The Hankook Ventus S1 evo4 X (K137A) is an ultra-high-performance summer tire purpose-built for SUVs and crossovers. Engineered with a next-generation rubber compound and advanced tread architecture, it delivers outstanding grip, braking confidence, and cornering stability in both dry and wet conditions. This 275/45R20 XL fitment carries a load index of 110 and a Y speed rating (rated up to 186 mph / 300 km/h), and features a black sidewall with Hankook's signature Vanta Velvet laser-etched sidewall finish. The BMW OE approval (*) designation indicates this tire meets the stringent original equipment specifications set by BMW.

Key Features:

• Chamfer Technology: Smooths tread block edges to distribute contact pressure evenly across the footprint, boosting dry braking performance and resisting irregular wear
• Optimized Lateral Shoulder Grooves: Secure tread voids during braking and heavy loads to expand the contact patch for improved wet braking — 7% better than the previous Ventus S1 evo3
• High-Performance Drainage Design: Circumferential and lateral grooves rapidly evacuate water to reduce hydroplaning risk and boost wet traction
• Concave Deformation Control: Minimizes contact gaps for 4% improved wet handling over the prior generation
• Tie-Bar Shoulder Block Construction: Creates a closed shoulder structure that reduces road noise during normal driving conditions
• Flat Side Profile: Provides stable, high-speed grip and predictable handling dynamics for performance SUVs
• Vanta Velvet Sidewall: Laser-etched, light-absorbing black sidewall texture for a premium aesthetic
• XL (Extra Load) Rating: Reinforced construction supports higher load capacity for heavier SUV applications
• BMW OE Approved (*): Meets original equipment standards for select BMW models

The Ventus S1 evo4 X (K137A) is a summer Ultra-High Performance (UHP) tire and should not be used when temperatures are consistently below 45°F (7°C). It is backed by Hankook's 30,000-mile limited tread life warranty and is the OE tire choice for luxury automotive brands including Audi, BMW, and Volkswagen. This tire is a direct step-up replacement for vehicles previously equipped with the Ventus S1 evo3.
