I am going to see if a welder friend of mine might be able to fill the hole, or maybe try to thread the hole and put a bolt in it with silicone and see if I can get it to hold air. I’m not sure at this point… If I can’t fix it, I will definitely see if I can duplicate the hole.
I was always taught to not weld on car wheels. To many what if’s can happen going at highway speeds. Especially if it’s an aluminum wheel I wouldn’t do it.
