For now, the X Tweel will serve only slow-moving vehicles. The factory, which began production in November, makes tires for machines like skid-steer loaders and lawnmowers (at high speeds, airless tires tend to vibrate and make lots of noise). But Michelin would like to extend the product line in the future. Ralph Dimenna, the vice president of Michelin Tweel Technologies, says he could see small utility vehicles like golf carts using airless tires in the next few years. Ultimately, he hopes to see automobiles join the revolution as well—though for now, you’d better keep a spare in your trunk.
