I found a leak on a friend's tire along where it meets the rim. I was hoping it was going to be on the threaded mating surface because then I would just plug it myself and then pump it all at home. Is there any way to fix this all at home without going to a shop that has a tire installation tool? Can I just deflate the tire to the point where I can detach it from the rim and then apply some sealant and pump it back up?
The yellow marks are pointing where the bubbles were coming out at the rim when I did a water test.
