I guess I'm biased based off what everyone else has said.
But 32"s are gonna be harder to fit than 31"s and are less popular, and I've heard that some companies are stopping/slowing production on them, so if you blow one it'll be harder to replace. And if you're gonna do enough lift to fit 32"s, you might as well do a little more to fit 33"s I'd say. If you have the gears... Idk. 33"s would be the very limit with 3.73 in my opinion, but realize you'll lose some acceleration and mpg in the city. I'm wanting at least 4.10s for when I plan on getting 33"s. 4.56 would be cool, but not in my budget...
Also, you'll have to watch your speedo and see how off it'll end up being.
EDIT; Just remembered, since you said not much offroading, you'll probably be fine with 3.73.
