Hypothetically, say I were to go from a LT235 sized tire(3.55 gears) to a
32" BFG sized tire(31.75" overall diameter), what size gears would I need
to put my truck's engine back within reseasonable power specs/rpms?

I know all the is available for GenII 4WD Dakotas, are the 3.55 gears, 3.90
gears(or is it 3.91?), or the 4.10 gears. Obviously I assume I will need
either the 3.90s or the 4.10, but what are the pros/cons of each? Remember
now, possibly these gears would be going on a daily driver.........so keep
that in mind.
Based upon various charts I have looked at, I think I could get away with
either the 3.91 gears or the 4.10 gears, but since gears/lockers/limited
slips are rather expensive........I want to do it and do it once, and be
happy with the decision.......if indeed I was doing a gear swap. Thanks for
any info.
