The tire/wheel reinvented - the iFlex

[XV1100SE]

Hankook has been developing a new integrated wheel/tire (no tire on the new design)

...concept of an airless wheel and tire all-in-one.

This new type of non-pneumatic tire is made from polyurethane synthetics with its tire being manufactured in conjunction with the rim as a one-piece. Hankook mentions it's considerably lighter than usual wheel + tire combos and does not need air at all. Fuel consumption and noise emissions are down compared to conventional setups, while vehicle safety is increased.... According to Hankook, 95 percent of the i-Flex's construction is recyclable.

Note, Hankook is working on even more advanced tire technology. Working with researchers from the University of Cincinnati, Hankook has developed an eMembrane tire concept that is capable of transforming its profile through internal structure changes in accordance with different driving conditions, such as in a busy city or on a race track.

 

For instance, when driving at high-speeds, the tire’s tread center extends to generate maximum ground friction through wider ground contact area, aiding grip. Conversely, when driving at low-speeds, the tread is designed to produce minimal road contact area and ground friction, whereby the tire's fuel efficiency is enhanced by reducing rolling resistance.

 

Hope they look at doing motorcycle tires.
