I would fix it. I would cut a 4" wide Oak board with a radius slightly smaller than the inside radius of the rim. Use a suitably large hammer, about 3 to 4 lbs. and smack it good. If you want to get real fancy, take the tire and rimstrip off and heat the general area well with small hand torch. Try for about 400F., but don't overheat it.
Follow this advice at your own risk. And there is some risk. Joe
