Hankook iON HT: an all-season Highway-Terrain tire for electric trucks and SUVs, built for range, load strength, and wet-road confidence

The Hankook iON HT is an all-season Highway-Terrain (HT) tire developed for electric light-duty trucks and full-size EV SUVs that spend serious time on paved roads. The design mission is straightforward: address the realities of modern EV platforms, including heavy battery packs, instant torque, and the importance of efficiency for protecting driving range. Positioned around the idea of “EV Endurance for the Long Haul,” the iON HT targets the practical balance high-mileage drivers want: stable, comfortable road manners, lower rolling resistance, and durability engineered to handle daily utility use.

Range and efficiency: reducing rolling resistance to travel farther

For EV owners, rolling resistance can directly influence how far a vehicle can travel on a charge. The iON HT emphasizes a range-minded approach with Opti-Cure technology designed to minimize energy loss during rotation, plus a Roll Lite Compound concept intended to reduce internal friction within the tire. The goal is improved efficiency on highway commutes and long-distance trips, where steady energy savings can translate into a calmer, more predictable ownership experience.

Durability and mileage: engineered for long-haul, high-load use

Electric trucks and SUVs combine high curb weight with strong acceleration demands, which can accelerate irregular wear if the tire is not optimized. The iON HT highlights Round Even Technology to help maintain more uniform contact pressure, Opti-Tread Technology to reduce uneven wear through block-specific rigidity optimization, and a ProDurable Compound approach aimed at improving wear performance. This long-life positioning is reinforced by a mileage warranty listed up to 80,000 miles (terms apply).

Wet-road confidence: drainage-focused design for rainy conditions

For a highway-terrain tire, wet performance is one of the most important real-world tests. The iON HT focuses on water management with flared lateral shoulder grooves and an optimized main-groove design intended to improve water evacuation and reduce hydroplaning risk. The practical benefit is more reassuring braking feel and steadier tracking on wet pavement when rain, standing water, and changing grip levels are part of everyday driving.

Load strength and peace of mind: built for heavier EV platforms

The iON HT is offered with an XL designation, highlighting a load-strength and rigidity focus designed to accommodate battery weight and utility use. For added confidence, it is supported by programs such as Road Hazard coverage and a 100-day free trial (program terms apply). The result is a complete EV highway-terrain solution: range-focused efficiency, long-haul durability, and wet-road control for year-round everyday driving.
