New York (CNN Business) Flying cars, though still very much science fiction, could one day disrupt Goodyear's tire business. If flying cars ever take over the roadways — and skyways — Goodyear would want a chunk of that market.

The company has designed an airless tire, called the Goodyear Aero, which would double as a propeller. The Aero tires would have bladed spokes that act as a fan allowing the wheels to flip upward and help propel a car into the air.

Goodyear's GT flying tire is currently just a conceptual design. Chris Helsel, Goodyear's chief technology officer, said the design is meant to spark discussion about transportation options for the future.

"With mobility companies looking to the sky for the answer to the challenges of urban transport and congestion, our work on advanced tire architectures and materials led us to imagine a wheel that could serve both as a traditional tire on the road and as a propulsion system in the sky," Helsel said.

Aviation experts doubt that the propeller-tire hybrid could ever make it off the ground. It would be tough for the wheels to satisfy the car's needs for breaking on the ground and withstand the high rotational speeds needed to lift the car into the air, Daniel Codd, a mechanical engineering professor at the University of San Diego, told CNN Business.
