Tire pressure for sand vs snow

Hey William, good question! For both, lower is definitely better, but I've found you can go way softer in snow than in sand. With snow, I drop mine down to the absolute lowest I can run without risking a pinch flat, maybe 3-5 PSI if you have fatties, because the snow compacts a little. Sand is trickier; you need just enough pressure, maybe 6-8 PSI minimum, to keep the tire profile stable and prevent the bead from rolling off when you turn aggressively.
