    That's a 35"...right now you have a 33".... measure to see if you have an inch of clearance everywhere when you turn. I'm guessing probably not. How did you get 3" in front? If you just cranked the torsions, go ahead and lower those a little, and probably replace ball joints, that's WAY too much.

    Cognito leveling & also my 285 measure 33.46 these 315 measure 34.6 so I'm gonna measure. I've seen 315 mounted on stock wheels with my setup I was just wandering.

    Stock wheels might work, but the offset is gonna be the problem. My 6'' lift rubbed with 35's and a 16x8 american racing whee Guaranteed that was with the bars sagged, which was probably roun 4-5 inches of lift then.

    I am not sure it is safe to run 315s on stock wheels. Max recommended for stock wheels is 285 which is equal to 11.22 inches. 315 = 12.4 inches. Your wheels are 9 inches so get another set of rims. As far as height, dont try to shove them on. Get a beefier suspension setup.

    EDIT: Its not the height to worry about, its the width.

    +1 315 tires are to big to run on stock wheels, it can be dangerous.

    he can run a 12inch wide tire on a 9inch wide wheel with no problems, Ive seen people running 14inch wide tires on 8inch wide rims and never have a problem except wearing the centers out of tires real fast but to each his own.

    And when something happens and he has to turn very abruptly, a bead pops, and he rolls his truck... We'll all say, Duntz said it was cool to do it.

    Just because he can, doesnt mean its a good idea. True that some 315 tires will fit. BUT........manufacturers have specifications for a reason. They didnt just come up with it on a whim. Get with the manufacturer of both the rim and tire to see what fits best.
