I knew it was a long shot, but after a couple of months of lots and lots of phone calls, lots of dead-ends, lots of research, I ended up speaking to someone named Keith Buckley in Akron, Ohio, at Goodyear Tires," Alonzo told AutoWeek.

 

"He knew about the car's history, we talked about it, and in the end, he told me that Goodyear's not going to want to get involved in this—it'd be too costly to reproduce (the tires). But let me talk to some people, let's throw something at the wall and see what sticks. He did that, and it stuck."

The tires fitted to the Golden Sahara II are relatively heavy, which makes them fairly impractical. The car can be driven at slow speeds in controlled environments.

​

"These tires are solid; the original ones were hollow and were able to fill with air," Alonzo said. "There are actually light strips built into the rim, and the polyurethane is poured over them—they weigh about 150 pounds apiece; I think there's nine gallons of urethane in each tire."

Henry Dumortier, vice president consumer for Goodyear Europe, said Goodyear's collaboration on the Golden Sahara II project was the company's first step in shaping the future of autonomous mobility.

 

On the futuristic side, Goodyear presented Aero, a theoretical non-pneumatic integrated tire/wheel concept that would double as a propeller to allow a lightweight autonomous vehicle to transition from road-going to airborne, even while on the move.

​

And more down to earth, Goodyear also showed a non-pneumatic tire/wheel structure called "DuraWeb" that it's proposing for use on the Olli eight-passenger autonomous shuttle vehicles, which are capable of operating at speeds up to 25 mph with a range of up to 40 miles, depending on load.

​

The Olli is a development of with Local Motors Inc., a Chandler, Ariz.-based "ground mobility" company. Goodyear struck an exclusive deal with Local Motors recently to supply the Olli shuttles with pneumatic tires—street-going models which it declined to identify—with an eye toward collecting data on the operational and maintenance needs of tires fitted on driverless vehicles.

 

The DuraWeb shown in Geneva appears to be a further development of a DuraWeb industrial tire/wheel unit that debuted in 2017 on a Bad Boy Mowers Inc. zero-turn mower.

Developed at Goodyear's Akron Innovation Center, the DuraWeb was described as having a thermoplastic connecting structure that provides both stiffness and flexibility to carry heavy loads and maintain a smooth ride while protecting turf.
