This week, Hankook TIre announced it has successfully completed its ride and handling tests for its latest non-pneumatic tire (NPT), iFlex. Hankook has been researching NPT technologies since 2011, and the iFlex is the fifth NPT concept tire that Hankook has released.

According to Hankook:

The company put the iFlex through a serious of rigorous tests designed to push the tires to their limits in five categories: durability, hardness, stability, slalom (zigzag) and speed. In the speed test, the electric car equipped with iFlex tires reached 130km/h. The impressive results in all five categories demonstrated that the NPTs could match conventional tires in terms of performance. At the same time, these results are expected to help the company solidify its position as a global top-tier tire company and, give new momentum to its future-oriented R&D capabilities.

Construction of the iFlex is centered on a new type of uni-material designed to maximize the tire’s eco-friendly potential. From a manufacturing standpoint, the material used during product construction significantly enhances the energy efficiency. From a product standpoint, the material allows the iFlex to be recycled with greater ease. Hankook Tire then went one step further, integrating new tire construction techniques to simplify the manufacturing process from eight stages to just four, thus further reducing the company’s carbon footprint.

This Hankook promotional video from 2013 shows the basic concept:
