I recently bought a pair of inner tubes and when I partially inflated one of them before putting it into the tire (only a few pumps with a floor pump), I noticed a portion of it was bulging out considerably. It looked like a snake who had swallowed a giant mouse, there was a huge bulge on one section of the tire. I went to get my camera to take a photo of it, but it then burst before I could take a photo.
Went back to the LBS and got a replacement tube, and when I partially inflate this one it also bulges quite a bit too, although not nearly as extreme as the last one that popped.
Is it normal for an inner tube to bulge out as much as this? I'm just worried this one will pop as well.
