Today I went through this situation. Rims are Vzan Action with Formula Hub 36 holes.
My rear tire was leaking. A guy patched up the tube and the problem persisted. I went to the bike shop and asked to check the patch, and as done, I went to a gas station, where I usually inflate it (only this year more than 2000km, most of the inflations were done at this station), and after inserting 65 psi and the valve, the tube EXPLODED.
Out of luck it was just that, but I bet everyone heard the sound 2 miles away. The tire was apparently no damaged. I returned to the shop with the intention of changing the tube (I already had another one, I wanted to mend that one to make it last longer), but on the way I saw the real damage. The side of the rim was EXPOSED, completely disabling the wheel.
At the bike shop, they said it was my fault for inflating in a gas station, and they did not offer me an apology, or even a discount for the assembly of a new wheel.
Soon I visited another bicycle shop where the owner informed me that the problem was that the tube was folded. And he also noticed that the side of the tire was damaged and that I would have to discard it, or it would compromise the tube in the future.
I would like some opinions from you. Was it my fault, afterall? If so, how can I check if its safe to ride?
I really like this tire and I did not want to get rid of it like that. It is being used since April. Can I still use it? Please check the images below.
Can I use the spokes of the old wheel? The hubs could, and should, be used, right? Or should I go ahead and buy a pair of new wheels?
Here are some images to illustrate.

Update: analyzing some Youtube videos, I think the explosion happened from excessive stress on the rims. Plus, it wasn't completely true, and brakes pads were touching them at some points.
I think that brake pads were bad positioned in the moment, or wore the wheels, or made then weaker in certain spots in the long run, making a crack or making the tube pop and explode in that direction.
I'm almost surely buying a new pair of wheels, which will cost me basically the same price of a single one in the bike shops that I went.
