A reputable local wheel repair company I used to do the TIG weld repairs for wheels like this would have probably been able to repair that crack, as long as it doesn't extend around the corner and past the tire seal safety bead. If so, their insurance wouldn't have covered it, and so they wouldn't have been able to repair it.

Although the crack can often extend further under the paint, the visible extent of the crack looks far enough away from the safety bead that I think in all likelihood, this should be safely repairable by a professional wheel repair outfit. So, I think you have a good plan. Hope it goes well for you. Those slow air pressure leaks can really be annoying.

Good luck, and by the way, any idea how this damage happened?
