If I can find a welding shop to do it that cheap maybe I will. I dont care about looks since its on the inner lip (cant see it). I might even take the tire off and have at it with my friends TIG. If Im going to replace it anyway, I wont care if I botch it.
I dont think 17" would help that much. 235/40 isnt that low profile. I drive on some crappy roads. I've hit some large potholes and it was probably an accumulation of them. None were recent and the leak started last week.
