The just showed a moon exploring vehicle. It didn't have air tires, as those would only explode in vacume. Is that true? I would just guess that they'd need less air molecules to be inflated sufficiently...
On some polar 4x4 trip, they had a cool trick to seat tires onto rims. They sprayed the beads with lighter fuel...and lit it! The air in the tire, which was quite loose on the rim, heated up instantaniously, expanded, and seat the tire at probably very low psi. I take they then just aired up the seated tire.
Don't try this at home folks! ...but I just might, with an old rim and tire...in the middle of a sandpit, extinguisher ready :-D
