    I want big tires. At least 38, maybe 40 or 42?? But I dont want to go wider than I absolutely have to. Does somebody use 5 inch
    backspacing and is the tire hitting the springs or frame or something like that? Lift 4" or maybe 6", no more than 1" body lift. I know there will be lots of work to make them roll, going to do rockcrawling and some serious stuff..

    With 5" backspacing you's be rubbing the tie rod end constantly. Just looked at my brother's 3/4 ton 10 bolt w/15x10s, 4 1/8 backspacing and 35 x 12.50s. Could go maybe 1/2 deeper. Mine D60 front, same wheels (but w/beadlocks), similar problem, except mine looks like the tire would hit first due to the 15" wide tire. Mine's a bit different though, since I have heims joints. I'd stick with 4 1/8, especially due to brake clearance issues. You already have to grind enough with these.
