Sure, there are new, exciting compounds that can make them stick harder, improve fuel economy, or make it to the next gas station after a puncture. But at their core, they’re still rubber donuts fitted to a metal hoop and filled with air. We can do better, so Hankook is out to reinvent the most important part of your car.

The Korean tire manufacturer has taken concepts originally developed by Bridgestone and other companies to the next level, combining the wheel and the tire into one cohesive unit that absorbs bumps better than their predecessors while negating the chances of ever getting a flat. The i-Flex is completely air-free, and even better, it has the potential to be a greener solution than traditional tires by both boosting fuel economy and being 95 percent recyclable.
