Are these the same as the ones Mark would have supplied ? As i have had problems with the ones i put on, twice on both rear tyres when inflated to 35psi after a short run the inner tube has started to push the tyre off the rim, now both tyres are out of shape and the beading has shreaded, I have only done about twenty miles on these tyres and the first time it happened thought i had'nt fitted them correctly and tryed it again with about 25psi in them, but these seemed to slow the speed down, so after i changed pressures the tyre came off rim and i have now put the tyres of my son's old bike to try. Has anyone else had problems, is it because of my weight ?
