I couldn't track down the old threads on greentyres, but I am getting closer to getting a cushion tire safety back on the road. It has 30" rims and does anyone have experience in stretching a 28" greentyre over a 30" rim? I know they have internal cords which might make this impossible and I would have to splice in a section. the 26" actually have a better profile. I just want to pin this down before I order them from the UK. Thanks in advance!
