Well I finally got the wheel off and dismounted the tire. I was hoping for absolution and that I would discover massive damage from road debris. However, that is not the case. Tire is slightly mishapen from flatenning at speed but there is not a mark on it. Beads look good and interior seems fine. The obvious culprit is the valve stem that was completely yet neatly torn off the tube. Rest of the tube looks great and I could not discern any additional holes or punctures. My 2 ounces of dynabeads are still happily rolling around inside the stemless tube. Soooooo, my lesson here as the man earlier states is to use new tubes everytime I mount new tires. I made special pains to make sure the external valve stem nut was not tight against the rim as I heard that can sometimes lead to shearing if the tire slips on the rim. I think I'll try to remount the tire with a new tube and see what that looks like. The tire might be deformed or out of round. Toe color is more normal with less swelling, pain and throbbing. Still bleeding at the nail but seems to be getting better. Course of antibiotics complete and a big bottle of percocet left over for a "rainy day". Any other words of wisdom, possible hypotheses or general abuse?
