Tokyo - Bridgestone unveiled working prototypes of its non-pneumatic thermoplastic tyres at the Toyko Motor Show in December. The company's 9-inch tyres can take loads of up to 330 lbs (150kg), according to 16 Dec blog from MSN.
The tyre is made using a recyclable thermoplastic resin to create the radial "spokes," which are interlaced on a special curve in both directions, Bridgestone said in a 29 Nov news release.
MSN noted that this was not the first time a concept tyre has been introduced. In 2005, Michelin introduced its flexible polyurethane Tweel, but as of yet it is not available on any cars, the blog reported.
