For years, tire makers have touted their investments in the exploration and cultivation of alternative natural rubbers.
Bridgestone, of course, is betting on guayule.
Continental, meanwhile, has been a pioneer in dandelion rubber research. And Goodyear, last year, said it, too, saw great potential in dandelions.
So far, though, Michelin's been mum on the alternative natural rubber front.
Just don't confuse that silence with disinterest. The company, after all, prides itself on its materials science scope and capabilities.
So it's not that the tire maker isn't doing anything. It's more that Michelin isn't ready to talk about alternative rubbers' potential just yet, Alexis Garcin, Michelin North America CEO and president, said during a media roundtable hosted by the tire maker Feb. 2.
"I can't disclose too many things around those secret processes and recipes," Garcin said about all the materials the tire maker is exploring in its pursuit of a 100-percent-sustainable materials tire, one it intends to bring to market by 2050.
