Hankook iON evo R (iK31): a performance EV summer tire built for grip, responsiveness, and efficiency

The Hankook iON evo R (iK31) is a summer tire developed to address the real-world needs of electric vehicles. In EVs, quieter powertrains make tire behavior more noticeable, while instant torque and added vehicle weight (often driven by battery packs) place unique demands on the tread. The iON evo R therefore targets a clear balance: deliver a sporty, precise summer driving feel while maintaining efficiency-minded performance that supports range, plus strong safety and confidence when conditions shift from dry pavement to rain.

Dry-road handling: a more responsive, stable performance feel

On dry roads, a performance EV tire must remain precise and stable as speeds rise. The iK31 uses an asymmetric tread design intended to strengthen grip and stability during spirited driving. The goal is a more connected steering feel for lane changes, corner entry, and stronger acceleration, while keeping behavior predictable and controlled for everyday use.

Wet-road confidence: traction and control when weather changes

Summer rain can quickly turn asphalt into a low-grip surface, especially at highway speeds. The iON evo R emphasizes wet traction through a drainage- and grip-oriented design approach, helping the tire maintain control as grip levels change. For drivers, the intended benefit is a more reassuring feel under braking and cornering on wet pavement, without sacrificing the dynamic character expected from a performance tire.

i Super Mileage and i Perfect Grip: traction consistency in real driving

Hankook highlights dedicated technologies for the iK31, including i Super Mileage and i Perfect Grip. The purpose is to deliver high grip across different surfaces while staying more consistent during quick launches or sudden maneuvers. In practical terms, this matters for performance EVs where instant torque can create abrupt responses if the tire is not optimized for EV driving behavior.

EV efficiency and everyday usability: performance built with range in mind

Finally, an EV tire must also support efficiency. The iON evo R is positioned to maximize summer performance while targeting everyday efficiency that helps protect driving range. Depending on size, fitments are often offered with an XL load designation and protection-focused details (such as rim protection), reinforcing peace of mind for drivers who cover serious kilometres. The intended result is a complete EV summer performance package: grip, control, braking confidence, and efficiency engineered for modern electric vehicles.
