I managed to pick up some 16.00s from GP and finally got around to dismounting them. Well, turns out that one was from a MaxPro M1235A1 Dash DMX and they have one piece run flats in them. That was interesting to remove. I see plenty of videos pulling them out of HMMWV tires which looks easy by comparison. Here is a little video of our fun with remove of such a big one. I think the run flat is 200lbs by itself.
