oh no guess again. I have already done this exact thing. Welll... everything but heat up the tire that is. Have to do it barefoot to get the right grip on the tire with your heel. And indoors so it can be on the carpet so you don't scarf up the rim. The Dawn on the last part of the bead was magic. One foot kept the tire coming back off the rim on the other side while the other foot applied persuasion to supplement my hands.
Thankfully those days are gone. BTW if you don't own one already, buy one of these. Not for use with Cushcore. Think of it as doing the job of a foot. Tubeless, tubed... doesn't matter just as useful for both.

I don't throw money away on tire gadgets because they are all crap. But this thing is the real deal. Makes almost impossible tires straightforward and normal tires a walk in the park.
