Goodyear’s latest concept tire, introduced at the 2018 Geneva International Motor Show, uses living moss to absorb moisture from the road, before converting it into oxygen through photosynthesis.

The concept, named Oxygene, has a unique structure that features living moss growing within the sidewall. This open structure and the tire’s smart tread design absorb and circulate moisture and water from the road surface, allowing photosynthesis to occur and therefore releasing oxygen into the air.

According to the World Health Organization (WHO) more than 80% of people who live in air pollution-measured urban areas are exposed to air quality levels that exceed WHO limits.

 “With more than two-thirds of the world population expected to live in cities by 2050, the demands on transport networks in urban environments will increase substantially,” said Chris Delaney, President of Goodyear Europe, Middle East and Africa. “Smarter, greener infrastructure and transport will be crucial in addressing the most pressing challenges of urban mobility and development.”

The wheel’s open structure absorbs moisture from the road through its unique tread and inhales CO2 from the air to feed the moss in its sidewall and release oxygen via photosynthesis. In a city similar in size to greater Paris with about 2.5 million vehicles, this would mean generating nearly 3,000 tons of oxygen and absorbing more than 4,000 tons of carbon dioxide per year.

Oxygene features a non-pneumatic construction that is 3D-printed with rubber powder from recycled tires. The lightweight, shock-absorbing structure provides a long-lasting, puncture-free solution intended to extend the life of the tire and minimize service issues, delivering worry-free mobility. Additional safety is ensured by the tire’s open structure, which improves wet grip by helping absorb water from the tread.

Oxygene harvests the energy generated during photosynthesis to power its embedded electronics, including onboard sensors, an artificial intelligence processing unit, and a customizable light strip in the tire’s sidewall that switches colors, warning both road users and pedestrians of upcoming maneuvers, such as lane changes or braking.

In addition, the tire uses a visible light communications system, or LiFi, for high-capacity mobile connectivity at the speed of light. LiFi enables the tire to connect to the Internet of Things, allowing vehicle-to-vehicle, and vehicle-to-infrastructure data exchange, which is critical to smart mobility management systems.
