Back 5 years ago I had this 077 repaired for about $100 locally at a place called wheel connection IIRC
Then my wife's old Envoy came with 20"s and one had a slow leak which I traced to a crack, no bend at all mind you. So I trace the end of the crack, drill a 1/8" hole all the way through. That's an old trick to keep cracks from spreading I've seen used on anything from music cymbals to structural steel. Then ground down in the crack a little bit and then my dad is a welder by trade so I told him to put a big thick hot weld over it front and back and I took it home and ground it back to shape and finished with some cutting compound on a polishing wheel so it was nice and smooth to help seal. Sounds intensive kinda, but in reality if you don't factor in drive time to have tire dismounted, them to your fathers shop the next town over, then home to grind/finish, then back to get tire remounted/balanced, it took well under an hour of actual hands on work.
