Sounds like you got slimed. What's aircraft tires doing on a tractor, you getting ready to fly over the up and coming new border wall? Maybe you should get a Northerntool manual tire changer around $75.00. That's what I've done, I do my own 7-16 AGs. I started putting tubes in after the first 6 months of owning my tractor. I tried the bead sealer couple times, didn't work for me, maybe because of heavy FEL work. So after a few times of tire up, tire down, I went with tubes and if I run over a nail, happened once, dismount tire and put a patch on.
