You can roll a typical MTB or road tire, even wire bead, into a smooth triple loop that won’t hurt anything, and is a lot smaller (good not just for shipping but also for carrying a spare with you on those epic expeditions!).
A smaller, heavier tire like the 24" Duro doesn’t fold as easily, so it might not work. I bought a 24" downhill tire that arrived folded into a too-tight figure 8, and the casing never really unfolded properly, so the figure 8 is definitely a no-no.
Here’s a photo of a 24x2.6" wire bead kenda kinetics tire rolled up; it’s not as heavy a tire as a Duro, though.
