When someone says they are "popping" their tubes, it tells me the tire is explosively blowing off the rim and putting a large hole or gash in the tube. As long as the tube stays in the tire, the tube won't POP. That means one of two things is happening:
1. You have a broken bead on the tire and it can't stay on the rim.
2. You are pinching the tube under the bead, the tube then works its way out during use and explodes.

For smaller holes, especially ones that repeat, you can always find the cause if you look hard enough. It may be a wire stuck in the tire, some debris, a rough spot on the rim, or bad rim tape that's exposing a spoke or a hole's sharp edge. Less commonly, a tube can be torn by manhandling the valve stem. I don't suspect this of being your problem since you'd have to be an absolute gorilla to do it every time. Most likely you're not properly mounting the tire and it's a pinched tube.
