285 70 17. will they fit

[86mk7]

What do I need to fit these on a pretty much stock truck. I'm looking at aftermarket 17s right now. I don't want to trim the front bumper either. Will a small torsion crank clear just fine

Anybody know.

yes they will fit just fine so long as you do not have some crazy offset or back spacing on your wheels

They'll be pretty mellow backspacing. Nothing realy crazy. Just some 17x8 or 17x9 with around 4in backspacing and an all terrain bfg retread style tire.

4 inch is more than stock so you may need to trim the valance and the inner rear part of the fender (I just cut that area out)

Well Damn. I'm not cutting anything since its all new. Guess ill stick to a 265 70 17 then. I thought I read that 285 would fit. I can d a small crank but I can't cut anything.

I have 8" of lift on 35s and still cut. It is inside the wheel well, no one is teh wiser and the average guy can never tell

4" backspace is what is getting you...if you look at rims that are 5"+, I've been told you can clear with just a little crank.

As a caveat, I'm just learning all of this myself and just passing on info...if someone here has actual experience (compared to me), pls chime in.

Check out the OBS "Exterior" forum on this site, i posted a few diagrams within the last few days that explain backspacing and what our rigs need to clear certain sized tires.

For what I've found in a black wheel that we like its always around 4.5 back spacing. I've found a few 5 inch back spacing tho to. The offset is what I don't get.
