Festus, you're confusing me with another poster. I did not replace a blown out tire with this spare. Instead, I had quietly rotated in this spare,
fully inflated it to the 65 psi sidewall pressure, and then had it fail two days later.
My best forensic guess is that the tire had gotten brittle sitting (covered) in the warm sun for 3+ years. This, combined with the bad bridge abutment encountered on its first day in service, led to a blowout. I also strongly suspect
overinflation as a contributing factor----since overinflation makes a tire more vulnerable to road hazards. (I believe 65 psi is simply too high for the actual 1800lb load on the tire.)
