Has anyone found the burst pressure? It is difficult to estimate, since I do not know if the tire are steel reinforced or maybe aramid fibers are used for reinforcement. The thread is very minimal so structural strength is provided mostly by the "plies". Steel and Kevlar have yield strength well in excess of 50,000 PSI (from memory) but I doubt that figure can be used as burst yield since it is not a simple loading. I would guess that before bursting the rim seal would fail.
