4.10's or 4.56's? (Yes I Searched)
My truck has a 5.2, automatic trans, and 3.55's. I want to upgrade my gears to either 4.10's or 4.56's. I'm not sure which ones to get. I do probably about 65-70% highway driving, and I'm afraid that 4.56's will kill my gas mileage on the highway. When my 285/75/16 tires are due for replacement, I am going with 265/75/16's. With the 285's, I'm at about 2000 rpm at 70mph. So, do 4.10's or 4.56's sound like a better choice for me? I'm leaning toward the 4.10's, but any help would be greatly appreciated!

Ok, that's what I thought. I am downsizing the the 265s when it's time for tires (not for a while, cause these are fairly new). I am in and out of the truck bed quite often, and I find the 265s to be a little easier to use as a step, and I think they look a little more "balanced" (just enough tire-to-truck ratio) than the 285s.
