Has anyone else tried green tyres? These are made of polyurethane foam instead of hollow rubber and are therefore puncture proof. I had a pair years ago on an old three speed bike and has no problems with them at all. I rode around on them for about eight months until the bike broke down due to a broken back axle. Then I dumped the bike but wished I had taken the tyres and kept them because they showed virtually no sign of wear and were not that much more uncomfortable to ride in than rubber tyres.
