Goodyear tyres with soy-based technology
Following extensive experiments, lab testing, road testing and more, Goodyear has introduced soy-based technology in its Assurance WeatherReady tyres, a broad line tyre that covers 77 % of cars, SUVs, crossovers, pickups and minivans. The company will expand its line of tyres containing soy with the addition of Eagle Enforcer All Weather for police vehicles that count on high-performance traction and handling.
According to the company, soybean oil could improve tyre flexibility at low temperatures, helping the rubber to remain pliable in cold weather and enhancing traction in rain and snow simultaneously. Additionally, the company discovered that soybean oil mixes more easily with rubber compounds and reduces energy consumption, which improves tyre manufacturing efficiency. In a typical tyre, the amount of petroleum oil is around 8 %.
According to Goodyear Chief Engineer, Polymer Science and Technology, Robert A. Woloszynek, about 60 % of that oil were replaced with soybean oil in the Assurance Weather Ready, which included 100 % of the oil in the tread compound. Goodyear’s cooperation with the United Soybean Board (USB) and breakthrough with soybean oil as a replacement for petroleum oil resulted in the prestigious “Tire Technology International Award for Innovation and Excellence” in the category of “Environmental Achievement of the Year” at the 2018 Tire Technology Expo.
