I called ReadyLift, their 4" lift doesn't fit 17" wheels so it won't fit my truck! They said they have only qualified it on 20" wheels so far and plan to qual it on 18" wheels. Now I'm going to have to look at the rough country 3" lift I guess.
I was thinking the same thing, might be able to go just a bit bigger than a 285/70/17 because it is raising the back up almost 2 inches in addition to 4" in the front!
Looks much bettetr with the nose up. What brand leveling kit did you get? I'm considering the ReadyLift 4" lift. ReadyLift says it will accomodate a 33" tire but I'll be interested to hear what tire you get on your rig with your 17 inch wheels because my wheels are the same size.
