35\" Mickey Thompons gear ratio

Just getting into 4x4. Don't know much 'bout mechanical issues, either. What I <font color=purple>do</font color=purple> know is that my 73K5 is getting 35" Mickey Thompson tires thrown on it, & that I'm looking for your recommendation of gear ratios to save the transmission. Unfortunately, this 4x4 beast will undergo lots of highway driving, so fuel economy's a minor issue. (Any K5 owner that thinks MPG is a major issue is driving the wrong vehicle!)

Re: 35\" Mickey Thompons gear ratio

Well..4.09, 4.10, and 4.11 can all be basically considered the same gear ratio, just different brands of axles used the sligthly different ratio just because the design called for different combination of gear teeth.
Anyway, something in that range would give you decent cruising rpm at 55-65 mph (not too high) and acceleration since you probably don't have an overdrive trans. If you are more concerned about off-the-line acceleration and power, than 4.56's work pretty good.
