It may be a moot matter in a vehicle weighing as much as the H2, but in snow and mud, it depends on whether you want to float or cut through. In deep snow [that, I got a LOT of experience in!] gravel, and sand it helps. Some northern expeditions use balloon tires at about 5 PSI. . .
I think the H1 has military specs for proper air-down in each condition -any H1 owners here?
