Now keep in mind I am no expert in bikes or any of the terminology.

I had a haro where the front tire was fine and the back was flat which was what I thought at the time..

I had added air into the tire and realized that wasn't the problem. Then, I changed the tube. I filled it up

then took it for a little ride down to a park about 10 blocks away. It was fine. But, then as I put it down

for a couple of minutes I heard a loud pop. It was the back tire again. So, yesterday I put my front and

messed up back wheels on a different frame and also changed the tire(used). I also put in a new tube. So,

as I was riding today, the air began to come out of my back tire. I don't know what it is now. Is it the

tires, or is it possibly the rim? Could a few loose spokes cause this to happen?

sounds like your spokes are pinching the tube inside the rim or the tire isn't properly seated. I vote on the spokes pinching the tube.

options? new wheelset, get the wheels trued, get better tubes. But more resistant tubes won't solve the issue 100% bring it in to your local bike shop and have them check it out.

Do you still have the old tubes? Are the flats occurring in the same place? It could be a spoke poking through the rim tape, it could be something sharp embedded in the tire itself is poking the tube, or there could be a sharp section on your rim (most likely around the valve stem, but it could be anywhere). You could do a long careful search, or you could sacrifice another inner tube (i.e., ride around the block until you get another flat) and then find where the hole in the tube is and figure it out from there.
