Sad story, may she RIP.
A side note, whenever you are inflating your tires never face the sidewall of the tire. Position yourself off to one side in case the tire or wheel fail.
They teach AF and probably Navy mechanics to face the tread of the tire, not the sidewalls in case the tire and rim come apart.
Wife WILL NOT inflate a tire of any kind.She gets very nervous even passing Big rigs.
We had a 1967 dodge Charger at the time that needed a front end alignment,but it was a Mopar,old and very expensive.
I bought cheap tire knowing full well they would not last long.
So one day as I was airing up the tires,the one on the right side exploded.
I have aired up numerous tires over the years and to me it was just another deal.Until the tire exploded in my face.Thank goodness I was not hurt,but it gave me a new respect for tires and the people who work with them.
PS,the tire did not look bad at all.
Now when we travel,i get past Big Rigs as quickly as possible. In West Texas,the heat will wear out any good looking tire.The remnants from the vehicles blown out tires are referred to as [Alligator skins].Some entrails last for miles.They are the only things buzzards do not eat.[To the best of my knowledge!]
