Tweel : The Airless Tire. Michelin, the worldâs largest tire maker, is developing an airless tire named Tweel (a combination of a tire and a wheel). Invented at Michelinâs North American research center in Greenville, S.C, this revolutionary non-pneumatic tire solves the common problem of getting a flat tire, as their invention cannot be punctured.
And those inventors have names that should be recognizable to anyone who's ever bought tires for their car: Michelin, Goodyear, Dunlop. Of these, none had so great an impact on the invention of the tire than John Dunlop and Charles Goodyear. Charles Goodyear and the Invention of Vulcanized Rubber None of it would have been possible without Charles Goodyear, who in 1844 -- more than 50 years before the first rubber tires would appear on cars -- patented a process known as vulcanization.
