I scored both sides of the tube with a razor to the point where I could sense I was hitting some of the rims. Let sit on the dash of my truck in direct sun and several times tried to rack/twist the tube to get it to split open along the scrores. Very hot. Had to use gloves. No dice. Couldn't get it to split apart. After 8 hours of sun, I used pliers and tore the top section off the tube.
