Goodyear Presents 63 % Sustainable Material Demonstration Truck Tyre at the IAA for Transportation
The overriding theme from the IAA for Transportation across the spectrum from the tyre manufacturers was one of sustainability, whether that be in the form of a pletho- advancements that reduce rolling resistance or, as is the case of Goodyear, presenting a demonstration truck tyre that is com- prised of 63% sustainable materials.
The 63% sustainable-material demonstration truck tyre includ- ed 15 featured ingredients across 20 tyre components with the
Ben Glesener, the Director for Tyre Technology Commercial EMEA for Goodyear explained, “This tyre is a showcase of where we are on that journey. Our ambition is to have a 100% tyre as soon as we can. In this demonstration tyre, the biggest portion of materials is renewable, and the smaller portion is recycled.
“One thing that is important to stress is that it is not just about -

mance. We only opt for any material if it is equal in performance or better.”
In terms of materials, carbon black is included in the tyres for com- pound reinforcement and to help increase their tread life. This has traditionally been made by burning various types of petroleum or coal tar-based products. Goodyear’s demonstration tyre features oil, end-of-life tyre pyrolysis oil, carbon dioxide capture and con- version, and a low-carbon methane pyrolysis process.
Meanwhile, some of the petroleum-based oils in the tyre were re- placed by the use of rapeseed oil. The use of bio-based rapeseed oil is in line with the company's goal of fully replacing petroleum-de- rived oils in its products by 2040. In relation to silica, this is currently an ingredient often used in tyres to help improve grip and reduce fuel consumption. The demonstration tyre at the IAA contained a variety of silica produced from rice husk ash, a by-product of rice
The polyester in the tyre is recycled from plastic bottles and oth- er plastic waste by reverting the polyester into its base chemi-
