I had an epic moment yesterday. I couldn't get the bead to set while mounting a new tire. I even used a compressor with no success. Air kept escaping. I was about to give up and install a tube. I unrolled the tube, and it hit me... Instead of putting the tube in the tire, I put it around the tire to hold the bead in place. "Pop! Pop! Pop!" It was magic! This really should be on the bottle of Stans.
