tire leak solve?

I have a pretty major leak (reair every 2-3 days) at the inner bead where the tire touches the rim. There is a small dent on the rim where there is a leak, but there are bigger dents elsewhere that doesn't leak. Is it the rim or the tire do you think?

And is there anyway to fix that w/o getting a new tire?

thanks

Could be a bad valve stem as well..... I had the same problem with one of my Iforged adapters and just got slapped a new one on, problem solved.

The dent or bad valve stem could be the issue. Have you checked the tires for any signs of nails or cuts?

A easiest way of figuring this out is a water dunk test. Submerge the wheel/tire in some water and see where it bubbles, then you got the source!

no I already did the soap test, and I KNOW for sure its a bead leak.

What Im asking is if I replace the tire will the leak go away? or the leak is prob caused by the bent lip and if so, what can I do to fix it.

Can you even fix bent lips on aluminum wheels?

Could be the just be the tire if you have other bends on the rim worse than the one your thinking it's coming from. What you could do is see if you have a tire shop that could possibly try remounting them with some bead sealant and see if that helps if not hell it could be either tire or rim....

its probably the bent rim. doesnt matter that larger bends are not leaking, the one where its leaking might be smaller but the lip is deflected more where it seals.
