I currently run 4.56 gears with 35" tires. My high gear (TF999) is 1:1 ratio. The reason that I suggested 4.10 gears is that my setup is too high for any long distance traveling on the freeway. At 65 mph, my engine is turning about 3000 rpm, which I consider too high for constant driving. So, if someone spends most of their Jeep time on the street (a lot of Jeep owners do), I don't think they'd be happy with 4.56 gears and 34" tires. And, as we all know, the fact that someone has 34" tires on their Jeep doesn't mean they do a lot of off-roading.

Fortunately, my CJ spends 95% of its time off-road. It gets trailered to the area where I'm going off-roading. So freeway driving is something I do very rarely, and then only for short distances.

Now, if my CJ had a manual tranny with an overdrive high gear, I'd have opted for 4.88 gears. I might have even chosen 4.88 gears if my transfer case had a 2:1 Low Range, rather than the 2.6:1 that mine does.
