Wheel backspacing help

ok so the wheels I want are method con6 , the 17x8.5 0/4.75 bs will have my tire sticking out around 1.5 inch’s I was told by someone on here. I’m fine with that, I want them to stick out alittle further.
My problem is I’m wanting to get the 18in wheels, the exact size and info is 18x9 18/5.75 bs, I have no idea what all this means, can someone please tell me how these will fit? How far will they stick out vs stock. The 17s are 8.5 Wide and 0/4.75, the 18s are 9in Wide and 18/5.75 bs. Can someone please make heads or tails of these numbers for me. I greatly appreciate it if you will.

Rough math says they will stick out 28mm more than stock with a +18 offset.

I think.

Yea it’s more than I can figure, the 18s are half inch wider than stock and have a 18 in front of backspace number which is 5.75..., the 17s are like 1.5 inch further out, I like that, but I gotta be for sure about the 18s if I’m gonna but them, don’t want them sticking out any further than the 17s would.

Wait, I think its 22mm further out than stock. Sorry. Want to see how far a 17x8.5 inch wheel with 0 offset sits? Hold on.

What’s the backspace on those wheels in that pic

It would be 4.75" backspace. This tool should help you. Stock wheels are 8.5 +34. Plug in your numbers and get your answers. I'm always here to help too.

I added 1.5" wheel spacers with the stock rims and had some rubbing up front on the inside at full wheel lock. Some very minor trimming fixed the issue, but thought this information might be helpful.

Does anyone know if a 18 by 9 with a 0 offset with 5.00 of backspace will fit on a raptor and not rub anything

Tire dependent you might get a slight rub but it will be minor (fender liner). Leveling the front should help with clearance as well.
