I've spent the last two hours trying to wrap my mind around some of the concepts discussed in this thread. Somehow this has turned into some high level math and engineering. It certainly has my brain feeling like it needs a nap. Probably because of my "calculations" the convo has taken a turn into the weeds of engineering, physics, and math that I for one can't figure out and has me feeling dumb too.
Which brings up another point, the educated and experienced engineers did a lot of calculations and work to design a jeep a certain way, I don't think that even they had all the "right" answers. Interestingly though if you run the numbers on gearing vs tire size for a stock tj (I think it is 30" tires and 4.10 gears?) and then for 33s and 4.56, it is almost exactly the same ratio as stock. Meaning it would get drive shaft, transmission, and motor speeds, relative to vehicle speed, right where the eggheads at Jeep put them. But loads of people like their jeep better geared lower and the entire aftermarket industry is there to "improve" stock designs. So who knows?!
