Tyre treads made with soybean oil-based rubber
The Goodyear Tire & Rubber Company is introducing a new tyre technology with some funding support from the United Soybean Board (USB).
The company has created a tread compound, or formulation, using soybean oil, which is cost-effective, carbon-neutral and renewable. According to Goodyear, the first commercial use of the soybean oil-based rubber compound is helping to enhance the tyre performance in dry, wet, and winter conditions. By employing soybean oil in tyres, the company found a new way to help keep the rubber compound pliable in changing temperatures. Tests have shown rubber made with soybean oil mixes more easily in the silica-reinforced compounds used in manufacturing certain tyres. This also improves manufacturing efficiency and reduces energy consumption, said Goodyear.
