A chap I worked with once had a pair of these.

I rode the bike and was dubious at first. They felt a bit harder than a pnumatic tyre at 100 psi.
The lower spec version might have been better.
He never got a puncture and after a year's use, they were compounded with small metal swarf curls because his route into work passed a metal recyling yard.
"Good on him." I said.
