In response to define blow out I had tread separation, damage to fifth wheel. When this happened I was second day on the road and had checked tire pressure before leaving that morning and all was good. I do not have a TPMS. I am looking at that also. A lot of mix reviews on them.
In response to axle alignment I pulled measurements and all is good. I have not been to a spring shop for this though.
In response to individual wheel weight I have not found a place that can weigh each wheel individually.
Thanks to all for advice.
