Assume, after deflating the marathon tyer, you pushed the bead into the rim's central channel?
Indeed, but a combination of ineptitude/inexperience (I rarely puncture, no idea why), probable weak hands and the shallow rim depth and velox cloth tape means there is not much central channel to work with. I am obviously going to choose to blame the rim central channel/cloth tape rather than myself ;-)
In my defence as a result of purchasing wheels, tyres wearing out and swapping tyre round I have uninstalled/reinstalled about 8 tyres in the last week and it was only getting the marathons off the a23s that caused me major grief.
