Maximise your EV's range with iON

Double the Advantage
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.

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.

Reducing Noise by Pattern Technology 1db
It offers improved noise performance by 1dB.

Pattern Noise Test result
The iON ST AS offers a quiet & 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.

Vibration Control Technology
Designed to absorb and reduce vertical impact shock when driving on road surfaces to provide a smooth, composed ride. Contact the ground gradually, which reduces the air pumping noise.
