Goodyear Creates Tire Made of 90% Sustainable Materials

Goodyear has created a prototype tire containing 90% sustainable materials that the company also believes could improve fuel economy and EV range.  Called a “demonstration tire” by the company, the tire is not yet ready for production, but has passed all applicable regulatory testing, including Goodyear’s internal testing, according the company press release.  
The demonstration tire uses 17 ingredients that are sustainable, or at least have a lower environmental impact than conventional tire materials, across 12 tire components.  One of the ingredients is soybean oil, which is used to keep the rubber compound pliable in different temperatures.  It replaces petroleum-based products, and is sourced from leftover soy from food and animal feed, according to Goodyear.  The company is already using soybean oil in some production tires including racing tires.
