Gosh... In the old days ya could just mount your tires, pump um up, and take off. Over the past few years I have had two tire failures that could have been catastrophic. On one tire the bead came completely off. It was a cheaper Chicom tire and the bead was thin. I could have caught the defect if I had made a pointed close inspection of the tire before mounting. The other was another ChiCom brand name tire that came apart longitudinally along one of the beads. On that tire there was no indication of defect before mounting. Both tires were mounted correctly and had normal tire pressures.
So you should first inspect your new tires as close as you can for defects. Then mount them and drive them around at least a few miles slowly on flat pavement. Gradually put them through thier paces. When you are taking corners at speed then deem them worthy and proven.
Like fire arms, all bicycles are unproven until proven otherwise...
