Hankook Tire has reported the successful high speed testing of its iFlex non-pneumatic tyre. The South Korean company has been developing the iFlex concept since 2011, and recently fitted its latest generation prototype tyre to a Kia Ray electric car in order to evaluate its performance at speed. The iFlex-shod Ray was driven through a slalom course at up to 130 km/h (80mph), and the tyre maker states that its airless tyre performed perfectly in all safety and durability tests.
