Off road tire pressure (for rocks)

[RuggedH2]

Stagger,

Have you ever popped a bead? You know that 15-18 is perfect, how? Lower pressure is better for rocks. There are hazards. That's why beadlocks have become so popular off road.

Unless you've gone low enough to pop a bead, I don't think you know the "perfect" answer for the H3. I see the common logic, but it's not so clear for every 4x4, many go as low as they can. Buggies commonly run 3 psi with beadlocks.

Thanks for "dumbing" it down for me.
