Just as a small hijack, that works for you & your rig, but I'd be wallowing all over the place at 15psi or less, and I'm not driving anything close to an F-600 either. When I bother to air down my '84 Xcab at all, 19 psi is my usual setting - even when on a "rock crawling" trail like Doran Cyn or John Bull or Dusy-Irshim. 30psi is what I normally take the Sub down to. Ideal air down pressure is related to every possible variable involved in the rig + driver combo. Or so that is MHO.
fantastic point. I know better than to make outlandish statements but I went and done it anyway, huh :elkgrin:
I never weighed my rangie but it was probably much lighter than the standard armored-up rover config. with 235/85 and 255/85 the sweet spot for me seemed to be around 13 psi.
and yes, Rob, the jeep is probably a good 2k lighter than your DII. Getting back to the rings - I doubt you'd be able to mount a set of the rings to your alloys, anyhow, right?
I am very much not a fan of all the aftermarket steel wheels, but it seems like if you're getting that much grief from abrasion and don't want to step-up your tire size, then moving on to a set of steel rims seems like the obvious and most cost-effective choice, no? And if you're not airing down past 15 psi then my quip about bead holding ability of the rim is probably moot.
food for thought
