I could say I've gone to 10psi at Bellanger Beach, Walpole, to get me out of the deep stuff on one occasion. But I thought it'd sound like bragging. [bigwhistle]

To the OP - These things will go anywhere. Ignore the "conventional" wisdom of old-school fourbies, and have a blast!

55 profile but who’s counting. I use 15 front 18 rear as a baseline. I’ve gone to 8psi both ends to get out of a bad beach bogging and they were fine (on factory rims at least).
