What caused this flat tire? I was riding my bike and the tire felt normal. I locked my bike, when I came back the tire was flat. Later I opened the tire, expecting to find glass etc, but there was nothing poking through the tire at all. I found was this big hole in the inner tube, what caused it?

More details:
The hole was at the side of the inner tube.
The front tire was nearly worn out, it was near the end of its life, I was planning to replace it this summer.
I also had a tire liner in that front wheel. So I wasn’t expecting a flat tire at all.
Any questions just ask.
That’s a blowout hole. Check the the rim tape to make sure no spoke holes are exposed and check the tire casing for sharp bits sticking out or spots where the casing has deteriorated and is weaker than other spots. Side of the tube leads me to believe it was a worn sidewall casing or something near the bead.
