Good informative vdo there RK, you can see how he ordered it so when it came time remove the tire from the rim he had the valve side up, facing him. And you can see, why; that valley inside the tire isn’t symmetric, but biased to the valve side of the tire. It showed he had removed the valve core when setting the bead, and didn’t have any trouble at all getting the bead to set. That’s pretty much my experience with car tires, not much trouble when setting the bead for them. He oriented the tire horizontally for the bead set, which I’ve done successfully; but I usually get it to set faster with the tire positioned vertically. The other thing he showed was something I do also, lube the surfaces. I just use a weak sol’n of liquid dishwasher soap and water. I always wonder if that water stays inside the tire indefinitely, or somehow evaporates out. If so, I don’t see how it could. But I never see any water inside an old tire when I open it up either. Life is indeed a mystery.
@Barkydog 's advertisement, well, hard for tire changing to compete with that … lol … Barky, suggest you pay someone to fix your wheel barrow tire, or just buy a new one, and otherwise just let that ad buttress you spirits …
