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?
