The H78-15 pressure (not for "normal driving," sand driving, or while using a snow-pattern tread) but for "high-speed driving," measured at 'cold inflation' (psi) -
FJ40, hardtop and soft-top: 26-front, and 30-rear
FJ55 'Iron Pig': 27-front and 31-rear
I figure that with a larger tire/rim combo, you could probably run pressures in the middle-to-high 20's (psi) on the highway? Maybe even lower?
One of my treads started a very slow-leak after some actual off-roading, a short off-the-trail adventure that resulted in rare varieties of cactus spines resembling whiskers sticking out of the sidewalls when I returned home, lol. I'll be at 13psi on one tire in a few months from now.
