Having Googled for this they all seem to be USA. I'm fed up repeatedly
getting punctures in my wheelbarrow tyre. Any suggestions as to how or

For push bike tyres, you used to be able to buy kevlar strips/hoops to
line the tyre. Perhaps such things are still available and could be
modified, or perhaps you could DIY something similar.
