Tiny crack on rim

haoleflip · Apr 21, 2014

I have the tiniest crack on the inner wall of my rim that is causing the tire to go flat every 3-4 days or so. What's the best way to repair it? I don't want to have to buy another rim.

weld it.

You CAN weld it - but your structural rigidity is already ruined. You'll be better of; and safer; simply buying a new rim.

I'm curious to know, how does a cracked rim cause a tire to go flat? Unless the inner tube is also somehow damaged, it shouldn't happen.

If the crack is at the edge of the rim and protrudes inward, and if it has cracked all the way through, then that would disrupt the bead and let air escape.

mostly because cars dont use inner tubes anymore??? even bent rims can leak too since it affects how the bead is sealing against the rim

i currently have a cracked rim right now that i took off. it was leaking very slowly. i repaired one a few months ago for around 100 bucks. ive taken off this one and plan to do the same. its the only ans safest way. to get it sanded down and re welded. if you can get a rim for under 200 i say get a new one. But if not take it to a professional.
