MikeofLA March 5, 2019 04:58 PM I can not see those small tires generating anywhere near enough lift. These would need to be much bigger. flyerfly March 5, 2019 07:11 PM I drew up something like this 30 years ago. Except my design had a lifting body for the car...But the tires/wheels were the same idea. Nothing new here. The blades on my tires were much bigger though. Mike said it right...the tiny blades on the goodyear one are not going to work at a normal RPM. AladdinConnolly March 5, 2019 07:39 PM @mike Larger definitely. But this whole concept is nonsense. And it is only out there for publicity. There is no way those spokes could have enough flex for the road and still be vital aircraft components. Aircraft have very high safety standards for obvious reasons and continuous road use on flexing components could never offer such safety guarantees. Of course goodyear knows this. They haven't even come out with a legit flex wheel that only works on cars despite decades of these concepts. But they get headlines so they are worthwhile.

VincentWolf March 5, 2019 09:41 PM As in Back to the Future II--Where were going we don't need tires! Just Tire props!

There's no way this prototype would get off the ground(surprised I was the first to say it). Tire wear would instantly create an imbalance. There would be easier options than creating a self balancing component just to drive this around...tread could possibly be stationary in flight, but that seems to be too much trouble than it needs to be. Unless the wheels are for taxiing, the tweel design this is similar to will have to overcome the vibration issues it faces at highway speeds..somewhere around 45mph and up I think . No credible sources..just from memory. And I haven't heard about any progression the last couple years. joe02 March 6, 2019 02:14 AM The balancing on two wheels and creating enough lift on just two wheels is problematic. A much better approach is to have 4 built in jack tubes beneath the vehicle that extend out enough to raise up the vehicle so that the wheels can rotate to the take off position and then begin to spin to take off speed. Race cars already use this approach.Here is a link to a youtube video showing how they work: https://www.youtube.com/watch?v=XgLx7QWbL8s The jacks would be retracted after liftoff and extended prior to landing. Jay Gatto March 6, 2019 07:25 AM Even more than driverless nonsense (it could be argued many cars already 'lack drivers'), flying cars, bikes and jetpacks are silly. anthony88 March 6, 2019 09:13 AM Maybe on a Goodyear blimp...maybe.
