Ed, agree with your analysis of under inflation. Have been more careful with inflation. I believe that was the cause of my tire failure. I have a spare tire tube on hand. I purchased it just before trying the tire sealant. Sealant is currently working OK. When tire craps out again, will install new tire tube. Thanks for your input re:sealant on tube tires info on corrosion. If needed, will have to bite bullet & get new tire/hub assembly; if I remember correctly the price was $35 when weld crack first occurred.
