I have been running Old Man Emu MD springs on all corners (approximately 3/4 inch over fresh stock height) for over 120k miles on my 01 SE. Initially I was running 255/70 Yokohama AT2's, as that is what I replaced the original 255/65 Toyo's with, had no issues at stock height. Once I needed tires again (after the spring swap), I went with 265/70 General AT2's which cleared the front struts by just enough to be comfortable with. I was recently due for tires again, spent about a month doing research, finally decided on the Falken Wildpeak AT3W'S (ordered from tirebuyer.com & had delivered to a local firestone, less expensive than anywhere else I could find). It turns out the Falken must run a little larger than average, as the 265's rubbed the struts. They actually had a set of 255's in stock and they were super cool about swapping to those. Had I wanted to buy & install wheel spacers, the 265's would've worked, but I didn't want to go that route. Keep in mind, any change in lift height has absolutely no effect on the distance between the wheel mounting surface and coil bucket on the struts, only wheel backspace/offset can play a role there. Over the years I ran 3 different manufacturers of 265/70 (Goodyear Silent Armor, Definity AT & General Grabber AT2's), all on the same set of factory wheels, without rubbing. Also, as far as the Falkens go, the 265's had a 4 ply sidewall, whereas the 255's have a 6 ply, so I'm probably better off in the end. I've had them for a few thousand miles now, in every type of weather (except extreme heat) and they've been impressive.
As far as your thoughts about lifting, although I love Steve's products, my suggestion would be to look into OME springs, as they have held up really well, do firm up the ride, but not to an uncomfortable point and they also handle a load far better than stock (no more bottoming out with some gear, or 2 people in the back). I'm approaching 130k miles on my MD springs and I'm preparing to freshen things up, as they're finally losing a bit of cargo carrying capacity (I frequently tow a loaded trailer or trunk full of tools), so I'm going with the md's again (approximately $170/set, but we'll worth every penny).
Sorry for the long winded read, but figured it couldn't hurt to offer all the information I could.
