The concept has been around for years, I guess its just more feasible with better Finite element analysis for design and new composites and manufacturing methods. :sip:

I see they are moving forward with this idea again.
Think it is GM that is going into this venture with them.

This rim-tyre concept can never be as good as what we currently have.
Currently the inertia-mass is only a layer of rubber, then air, then the rim/wheel but this is uncoupled by the air - which practically speaking has no mass.
Such reflects in the reaction time hence roadholding capacity.... and a flexi-rim plus solid tyre will never be able to replicate this.

Plenty years ago we probably also said certain things will NEVER happen.
I like to dream of the future  :thumleft:

It doesn't have to be as good as what we have now. We don't need 200kph vehicles at all (bikes excluded  :biggrin:).

They can develop the wheels and then develop vehicles that can use them. Tractors and other commercial vehicles come to mind.

GM build cars, don't they?

Huh? Can the slim manne tell me how many kgs of air in a17" motor tyre pumped 2.5 bar??

I'm as thick as a brick but the Interweb tell us that:
At 0 C and normal sea level pressure a mole of gas occupies 22.4 liters, so a cubic meter of air has a mass of: 1000/22.4 0.02896 = 1.293 kg
As I was referring to the displaced air by the outer tyre this when suspending is what, half a cup full?
Hence negligeable, never mind the 2.5 multiplier
 ;)


Edit: Woody, your nick & viagra go hand in hand..... is that a pun or punt intended?  ;)
