Goodyear unveils tire made with corn

At Europe's annual auto show, Goodyear announced the world's first tire made from a compound derived from corn.

The Goodyear GT3 tires uses a starch-based filler material called BioTRED. This BioTRED compound partially replaces the conventional black carbon and silica used in tire production. Designing engineer Filomeno Corvasce says the tire has these advantages:


  • A lower rolling resistance which results in lower fuel consumption.
  • Noise reduction.
  • Lower carbon dioxide emissions .
  • Less energy consumption during the production process.



Unlike today's tires, the BioTRED uses renewable compounds. The starch used in the tires is made from corn using a process that is similar to the one used in food industries. Then, two additional steps convert it into micro-droplets of starch and then into a biopolymeric filler used in the production of tires.

Goodyear is introducing the GT3 tires in Europe and then plans to make them available in other regions.
