MICHELIN LETS THE AIR OUT OF FUTURE TIRE INNOVATION

超屌啦！透明汽車輪胎咧！ 完全不需要打氣，也不用擔心被釘子戳破輪胎，在路邊也不會被人惡意放氣啦！








這項技術叫做Tweel

Benefits of Tweel:
The heart of Tweel innovation is its deceptively simple looking hub and spoke design that replaces the need for air pressure while delivering performance previously only available from pneumatic tires. The flexible spokes are fused with a flexible wheel that deforms to absorb shock and rebound with unimaginable ease. Without the air needed by conventional tires, Tweel still delivers pneumatic-like performance in weight-carrying capacity, ride comfort, and the ability to "envelope" road hazards. Michelin has also found that it can tune Tweel performances independently of each other, which is a significant change from conventional tires. This means that vertical stiffness (which primarily affects ride comfort) and lateral stiffness (which affects handling and cornering) can both be optimized, pushing the performance envelope in these applications and enabling new performances not possible for current inflated tires. The Tweel prototype, demonstrated on the Audi A4, is within five percent of the rolling resistance and mass levels of current pneumatic tires. That translates to within one percent of the fuel economy of the OE fitment. Additionally, Michelin has increased the lateral stiffness by a factor of five, making the prototype unusually responsive in its handling.


Future of Tweel? Technology:For Michelin, Tweel is a long-term vision that represents the next step in a long path of industry-changing innovations. Fifty years ago, Michelin invented the radial tire and there is no question that radial tire technology will continue as the standard for a long time to come. Michelin continues to advance the performance of the radial tire in areas such as rolling resistance, wear life and grip. In the short-term, the lessons learned from Tweel research are being applied to improve those conventional tire performances. In the future, Tweel may reinvent the way that vehicles move. Checking tire pressure, fixing flats, highway blow-outs and balancing between traction and comfort could all fade into memory.
