Bridgestone's Airless Tire Prototype

Bridgestone showed off a second-generation prototype of its Air Free tire at the 2014 Paris Motor Show. The company is developing tires that use slanted resin spokes instead of a cushion of air to absorb shocks.

Why mess with the proven design of tires? Of course, there’s no such thing as a flat tire, but the main reason is to improve recyclability compared to conventional tires, said Olivier Monbet, leader of Bridgestone’s technical department for France and Benelux.

“Every part of this tire is recyclable,” Monbet said.

When the rubber part of the tire wears out, a new one can be fitted by heating it up and slipping it on, says Olivier Monbet, leader of Bridgestone’s technical department for France and Benelux.
