While I have had a variety of alarming blowouts with latex tubes over the past 3-years, in almost all cases prior to switching to Zipp Firecrest wheels, the cause of such blowouts was a result of improper installation and/or lack of diligence in checking for pinched tubes after the wheels had sat idle for a few days and lost pressure. It has been my experience that when rims with narrower internal width (Reynolds DV-46 and SDV-66 in my case), coupled with high performance clinchers/tires with supple casings/high TPI, then such checks should become a normal ritual prior to re-inflating after a period of non-use. The reason I think is that as such tires age, the casing at the bead gets looser on the rim and as the tube leaches air and gets closer to ambient pressure, the tire bead has a tendency to pull back from the rim leaving a gap which allows the latex tube to migrate into void which in turn gets pinched the next time it is inflated.
