rxinhed, would using a small spacer (10mm or less) be reasonable to get scrub radius near zero (i.e. closer to stock on monties, and to help with more even tire wear) after switching tires and wheels to a "tall and skinny" combo? Also, which do you think is more pertinent: the increased steering effort with a larger scrub radius (positive or negative) or the increased unsprung mass and leverage created through the use of a wheel spacer or lower offset wheel?

I suppose it may be application dependent, since a crawler may want both a wide wheel with tall sidewalls, but also a minimal increase in steering effort. Alternatively, an overlander that stays on tarmac and smooth logging roads may prefer the traction/fuel economy benefits of switching to lighter/less wide wheels/tires and may never see increased maintenance from the increased steering effort/wear.
