Because my shoulders are too knackered - I carry one of these........
I tried a VAR on my old 406 Durano fitted wheels on my last trike - it snapped.
Generally speaking I can pretty well reseat any tyre without tools as it is all about technique.
My technique is to ensure as much of the tyre is in the wheel well as possible and if necessary keep it there with toe clip straps. Once you have the very last bit of tyre to get onto the rim, rotate the wheel until it is at the top, then grab the wheel with both hands next to each other at the area of tyre that needs seating, hold the wheel so that your fingers are holding the rim on the side of the wheel furthest away from you so that the heel of your hands are against the part of the tyre still to be seated. Finally, while squeezing the rim tightly twist your hands upwards from your wrists.
This method exerts a lot more pressure than you can exert with your thumbs and reduces the risk of damaging the inner tube with tyre levers.
