When I read the original post, I couldn't help but think, "Put a boot on the inside and put in a tube". Then I saw the pictures. Man, Oh Man. At my ripe old age I thought that I'd seen or heard just about everything but I've never seen anything like that. What a mess. I'd have thought that the ripper would have laid against the tire and been kicked back out when it hit the first lug. Obviously not!!!! When that box blade swung over and hit the tire, it must have hit it HARD.
The whole of life is a learning experience, it's just that some lessons are harder than others. Man, I feel for you!!!!!!
