Bicycle Mechanics - lump in tube

hi i just fixed a puncture on my bike and when i pumped it up it had a lump in the back

is there any way to fix this or do i just have to buy a new inner tube??

I'm not sure what youre asking.

I dont know about humps in tubes, but if the tire if bulging off the rim that means the bead is not seated correctly, and it will soon explode.

If there is a hump in the tire that means you have a broken tire casing. I would buy a new tire.

If there is tube protruding from the tire from a hole that means youre tire is no good, and your tube will soon explode.

one side of the tube is bulging out and the other part is normal sorry if i wasn't specific. When i put the tube back into the tyre the tube bulges out

Heh, dumb question...

Is it the right size tube?

If yes, I would suggest deflating and re-seating the tube and bead.

When i put the tube back into the tyre the tube bulges out
How do you know that? With the tire around it you can't see the tube.

Do you mean that the tire bulges out?

it is the rigth size tube and ik pumped up the tube before i put it in the tyre

OK, let me try.

1. Prior to putting the tube into the tire, you pumped it up.

2. When you did, one part developed a bulge.

Sounds like it would be OK, and maybe you pumped it up too much. Or, quite possibly, when unrestrained by the tire, they all do that because some parts are thinner than others.

Many tubes bulge oddly when pumped up outside the tire - guaranteed it will if patched, as the patch keeps the tube in that area from expanding as much. Put it in the tire and don't worry about it if the tire looks even.

ok thanks for the help
