Subscribing. I think what you're doing is outstanding and will be worthwhile! This is looking to be an important thread for those of us who have offroad ready vehicles looking to boost our FE. The great thing is that small gains (.5 - 1 mpg) are huge to us
Over the course of 10-20 years, a smaller 4wd would cost less overall... though I doubt you'll drive your luxury Exploder that long
Tires - look at 33x10.50R15 BFG AT KO's. My K5 will be getting these for all-purpose driving. A reduced contact patch for less drag, greater psi on the tread when offroad, reduced weight over a 33x12.50 and a greater height for reduced rpm on freeway. You'll be quad-winning
