HANNOVER, Germany (Sept. 25, 2014) — Continental A.G. has begun building test tires made with rubber derived from the latex of dandelions and projects serial production using the rubber could start as soon as in 10 years.
Continental displayed the first test tires made from the dandelion-derived rubber at the International Motor Show (IAA) Commercial Vehicles in Hanover this week. Conti has coined the name Taraxagum, derived from the botanical name for dandelion (taraxacum), for the material.

The tires shown, winter passenger tires, were built with treads using Taraxagum in place of conventional natural rubber. Continental said this development takes it closer to reaching its goal of making tire production more sustainable and less dependent on traditional raw materials.
“After several years of development work together with the Fraunhofer Institute, we are excited to take the first dandelion tires to the road,” said Nikolai Setzer, member of the Continental executive board responsible for the Tire Division.
“In order to make the best use of the crop yield produced to date, we decided to build passenger car winter tires, as they contain a high portion of natural rubber,” he said.
The tires will undergo thorough testing at the Contidrom proving grounds near Hanover as well as in Arvidsjaur, Sweden.
Continental said it intends to industrialize dandelion rubber and introduce it to serial production within the next five to 10 years.
