Airless Tires - Lower Rolling Resistance & Lower Maintenance?

[Piotrsko]

Instead of airless how about foam filled? Been the latest rage in forklifts since 1980 and the foam people can taylor densities for any load.

The reason they are supposed to last longer: the contact point is more flat

They have foam inserts for motorcycle tires used off-road. The problem is they don't last long at high speed. The flexing builds up heat and kills them.

Michelin says 6 months max life, 80 mph max, and keep them under 40C.

I want the ability to fine tune the pressure, and therefore characteristics of the tire.

I've got tire puncture repair down to about a 5min process from stopping, to going again.
