Bikemanforu loses street cred because he's mounted that tire backwards. Sure it'll still work that way, but ... really? He can't get it right for a how-to video?

I go all the way around both sides, pushing the bead away from the rim and looking down in. If I see the tube, it's only because the tube isn't up inside the tire where it belongs, and that needs to be fixed. After that you can 'massage' it; but you probably won't have to.
