Michelin aims to eliminate flats and blowouts with its remarkable Tweel concept, an airless one-piece wheel-and-tire combo that could soon enter production. The Tweel's hub connects to polyurethane spokes that assume the shock-absorbing role of a traditional tire's sidewall. The spokes are bonded to a reinforced rubber tread band that can be as specialized as today's tires. By varying the thickness and size of the spokes, Michelin can generate a wide array of ride and handling qualities.
