Hankook 1025004 Ventus S1 evo3 EV K127E 235/55R20 105Y XL Summer UHP Tire

The Hankook Ventus S1 evo3 EV (K127E) is an Ultra High Performance Summer tire purpose-engineered for battery electric vehicles (BEVs). Designed to handle the unique demands of EV powertrains, this tire delivers nimble handling and reliable traction on both dry and wet roads while prioritizing low rolling resistance and cabin refinement.

EV-Optimized Performance:

• EV-Tuned Traction: Specially formulated to manage the instant torque and rapid acceleration of electric motors, minimizing slippage and irregular tread wear common in BEV applications
• Asymmetric Tread Design: Stiff outer shoulder blocks with an optimized contact patch deliver confident cornering grip on dry roads; inner blocks increase pitch variation for improved wet braking performance
• Interlocking Outer Grooves: Secure wet grip and actively resist hydroplaning on slick surfaces without sacrificing dry handling capability
• Low Noise Construction: Minimized lateral groove volume reduces road noise—critical for EVs where engine noise is absent and tire noise is more perceptible
• Aramid Hybrid Belt: High-strength aramid cord construction reduces tread deformation under centrifugal force at speed, neutralizes lateral cornering loads, and enhances high-speed handling stability
• Extra Load (XL) Rated: Reinforced construction supports the added weight typical of battery electric vehicle platforms
• Black Sidewall (BSW) with clean, modern profile
