Hankook 265 45 R20 108Y Ventus evo K137A SUV 2025

Hankook Tyres positions the Ventus evo SUV K137A as an ultra-high-performance summer tyre for modern SUVs. The exact 265/45 ZR20 XL specification is listed with an EU rating of C for rolling resistance, A for wet grip and 71 dB for external noise. Hankook also lists this size as originating from Korea, with no M+S or 3PMSF marking and no run-flat or Sealguard construction. 0

Controlled Steering and SUV Stability

The 265/45 profile gives this tyre a useful middle ground between sporty response and SUV comfort. Its reinforced XL construction helps limit excessive sidewall movement when the vehicle is loaded or pushed through a faster corner. The result is a more composed steering feel, particularly during lane changes, motorway driving and long sweeping bends. The wide contact area also helps the tyre maintain a planted feel when the vehicle's weight shifts during braking or cornering.

Wet Grip and Braking

Wet-road performance is a major part of the Ventus evo design. The exact 265/45 R20 version carries an A rating for wet grip, while Hankook's tread and compound development focuses on improving water evacuation and maintaining contact with the road. Hankook states that the Ventus evo generation achieves shorter wet braking and improved wet handling compared with its predecessor. 1

Dry-Road Performance

On dry asphalt, the K137A is intended to feel more precise than a conventional comfort-oriented SUV tyre. Its reinforced shoulder structure and stiffened profile help the tread remain stable when lateral forces increase. This is particularly useful on heavier SUVs, where a softer tyre can feel less immediate during direction changes. The Y speed rating also makes the tyre suitable for high-speed road applications when that rating matches the vehicle's approved specification.

Ride Comfort and Everyday Driving

Although the Ventus evo SUV K137A has a performance-oriented character, the 45-series sidewall gives it more cushioning than an ultra-low-profile performance tyre. It can therefore work well as a daily SUV tyre for drivers who want sharper handling without moving to an extremely stiff setup. The 71 dB external noise rating is also consistent with a road-focused performance tyre rather than an aggressive off-road design. The tyre is intended for summer use and is not marked for severe winter conditions. 2
