Hankook iON ST AS Reviews

Thanks to iON innovative technology, the iON ST AS has pushed the limits to bridge the gaps between grip performance and noise / tread wear.

Extended Tread Life - ProDurable Compound . Composed of advanced fillers and flexible rubber materials, ProDurable Compound provides higher mileage without compromising snow performance.
Even Tread Wear - Round Even Technology. Tyres equipped on electric vehicles wear out approximately 20% faster with uneven wear than on ICE vehicles. iON ST AS achieves uniform contact pressure by optimising contact structure through Round Even Technology. The iON ST AS provides longer usage and less replacement.
Further Reduced Rolling Resistance - Opti Cure Technology. The iON ST AS achieved the highest grade of LRR performance by applying Opti Cure Technology which improves all parts of the tyre equally.
Drive in Peace - i Sound Absorber Technology. Electric motors are almost soundless which results in the driver hearing more noise from the tyres. With i Sound Absorber Technology, the iON ST AS offers a quiet and pleasant ride in all speed ranges.
Smoother Ride Comfort - Optimised Multi-Pitch Sequencing through Opti Pitch Technology. Tyre noise can be drastically reduced by applying Opti Pitch Technology. The iON ST AS has optimised the number and size of pitches to let you hear what's important.
