It's the Tire swing on steroids. 4X4 .250 wall square tubing with parts from my old 12 bolt to make the pivoting and rotating hanger. PURE BEEF!!!! It's the best use of a 37" Goodyear tire I have ever seen. I'm not sure how heavy it is but it weighs a TON!! Thanks to Jason for helping me install it. Without him I would probably have gotten a damn hernia The best part about it is that it was just about free. I had all the steel left over from soe of my jobs and the tire was ruined anyways. Only thing I had to pay for was the rope and hooks at the top. Everything else I had.
