My ears rang for a good 5 minutes, and worst of all the blast was so bad it actually ripped the bead off the tire and the tire was shot. So now when ever I buy new tires I also buy new tubes. Rubber sadly degrades and breaks down over time.

I’ve seen tubes rupture because of a bad rim strip and those are relatively quite “pops”, not loud bangs.

A very loud blowout is related to either the tube being trapped between the rim and the tire where it forces the tire off the rim and ruptures. That’s a very common mistake and is always user error. I’ve done it but I’ve never blamed the tire.
