I have a friend who owns a shop that fixes heavy tractors...he tells me those big 8 wheel pivot-type tractors are very closely related to 18 wheelers in terms of the drivetrain. For whatever reason, they are looked down on, somewhat, for that reason in the tractor world. I think the idea is that a 'real' tractor would use a more substantial engine/transmission.
Anyway....I took one of the tires off and it was heavy AF. It weighed in at 332lbs, and that was after I had already let it drain with the valve at the 6 o'clock position last week. I removed the valve core to let the air out and was surprised that more water issued forth....quite a bit. I let that drain for a while, then I broke the bead easily with the KenTool slide hammer. I tried prying the tire off the rim, and it came off easily as well. Used the shop vac to suck out the big stuff, dried it all out with a towel and fan, then reassembled. 174lbs...a savings of 158lbs. That's very satisfying. I bet I drained another 150lbs (or more) last week so that's around 600lbs less weight on my soggy mud field.
By the way, it was a tubeless setup.
Thanks everyone!
