Goodyear Tire & Rubber Co’s new Unisteel tyre (CI No 1,798) is claimed to use computer technology and radio frequency communication to talk to those monitoring its performance and the company says it has mastered the techniques to build the microprocessor into the tyre itself in a way that will withstand the intricate and complex steps of the manufacturing process: it reckons that it can save truck fleet operations substantial sums of money through improved management of truck tyre maintenance and protect against tyre theft, so no, it doesn’t actually change itself – sorry for those parents hoping it would lead to an intelligent nappy – diaper – that changed itself.
