As title states.. does this even make sense?? Will it even fit!?!?! 17x8 wheels with 4in back space and -12 offset... what problems will I run into... I can get them fkr a really good price .. they are vision 8 Steelies and yes I know they are super heavy but the deal
Is pretty good.. if I can run them I think I will!! Anyone have expertise or experience with these size or similar. ?? any input appreciated!!

Doesn’t clear front calipers??? That doesn’t make sense, these wheels are pushed out away further making more backspace no? Can anyone else chime i. Before I jump on these and possibly make a mistake ...

It's not the backspacing, its the shape of the center disc. A flat transition from the hub to the rim does not work.

The calipers protrude outboard past the wheel-mounting surface of the hub enough to hit the wheel if the wheel is not a bit convex, like the inside part of a donut (a torus).

The ones linked in my response hit the caliper. If your wheels are shaped like those, they will not work.

Make sure you get a return policy before you buy those.

Don’t they All have to have a flat part on hub? To make constant contact where they bolt on no?

Yes, but the part of the wheel between that area and the rim has to be convex in profile, or it will interfere with the caliper.

Caliper in red, hub light blue, wheel yellow (and dk blue). Crudely drawn in from the side perspective of a wheel.

I've ran 17"x8" wheels before.
Mine had 4.5" backspacing and +0mm offset.

Your wheels would be the same as mine, but sticking out further. Being that both wheels are the same width, we can simply conclude that it should fit (if they were the same design as mine), but yours having more "poke".

You'll have 12mm more "poke", and thus, 12mm less backspace.. or in this case, about 0.5" less of backspace. Your wheel moves "outward". The important aspect is really the design of the spokes.

Anyway, I'm on 17"x9" now and I have even less backspacing lol

PICASSO himself couldn’t have drawn it better!

Sounds really good!
 
Small update: as a few of you have said.. the wheels did not fit , but I had a spare 1.25” spacer and they definitely did fit!! Was just a test fit... will be installing my Eibach lift in a couple weeks and then throwing these wheels on!!! Then off to some trails I go!!! Pics will be coming soon .!

You are going to rub with that setup.
