The Hankook iON FlexClimate SUV wants to be that one tire you fit on your electric SUV and then forget, quietly humming along through rain, cold mornings and long motorway stretches. At least on paper, it promises calm, range-friendly rolling and all-season convenience.

All-season focus for EV SUVs

With the iON FlexClimate SUV, Hankook extends its dedicated iON EV tire family into the all-season segment for electric SUVs and crossovers, targeting drivers who want to avoid seasonal tire changes while keeping rolling resistance low for range.

The tread pattern uses a V-shaped layout with multiple sipes and wide lateral grooves, designed to evacuate water and offer snow traction while keeping a relatively closed shoulder for reduced noise on dry asphalt.

What the construction promises

Under the tread, Hankook uses its iON-specific compound and a reinforced carcass to cope with the high torque and weight typical for electric SUVs, aiming to limit tread squirm and uneven wear over many quick launches.

A sound-absorbing foam layer inside selected sizes - branded as Hankook’s Sound Absorber technology - is intended to cut the droning cavity noise that can become clearly audible in otherwise quiet EV cabins.

Size range and fitment options

The iON FlexClimate SUV initially targets common 18 to 21 inch sizes used by popular electric SUV models in Europe and North America, such as the Tesla Model Y and Hyundai Ioniq 5, with further dimensions planned depending on market demand.

Load and speed ratings are tuned for EV use, with high load indices and speed ratings up to H and V, aligning with typical manufacturer requirements for mid-size and premium electric SUVs.

Driving feel in everyday use

On paper, the FlexClimate concept suggests a tire that should feel planted and quiet at motorway speeds, with a slightly firmer response over small bumps due to the stiff carcass that supports heavy battery packs.

Drivers can expect a compromise between summer-tyre sharpness and winter-tire pliancy, which in practice often means neutral, predictable steering rather than razor-quick turn-in, but with reassuring traction on wet, cool days.

Efficiency, noise and trade-offs

Hankook positions the iON range as optimized for low rolling resistance, and the FlexClimate SUV is no exception, aiming to preserve EV range versus conventional all-season SUV tires while still achieving a competitive EU label rating for wet grip.

The all-season tread blocks and numerous sipes inevitably introduce more movement than a pure summer pattern, so drivers in hot regions may notice slightly softer steering feedback and marginally longer braking distances on dry, warm asphalt compared with a dedicated summer EV tire.

Availability and pricing picture

Hankook is rolling out the iON FlexClimate SUV primarily across Europe and North America, focusing on replacement sales through tire specialists and online platforms, with OE fitments expected to follow as automakers expand their EV SUV ranges.

Street prices will vary by size and region, but buyers should budget around the mid to upper segment of the all-season category, reflecting the EV-specific construction and noise-reduction features rather than aggressive budget pricing.

Company context and listing

For Hankook Tire & Technology, the iON FlexClimate SUV fits into a broader push to grow higher-margin EV tires while navigating shifting trade rules and supply chains, including responses to tariff changes in key export markets.
