At the start of my KLR period, on long trips I actually used to carry a C clamp (to break the bead), a pair of them 10” tire irons, and a tube. Filled up half a saddlebag just with that.
Then one day I actually had a flat, and there I was with my tools, c-clamp, tire irons and tube, standing by the side of the road looking at a 450lb motorcycle with no centerstand......
Had a flat many years ago and every idea we could come up with to break the bead failed miserably even with the wheel/tire in my big bench vice. Finally succeeded by heating the rim with a torch. Looked like the mfg. had used a glue/sealant all the way around the 40 spoke rim.
Why ?
