What do I have to do to get these rims to fit?

so do the Raptors you mentioned have the correct bolt pattern? if so, go with the -6 offset, that's very very close to spidertrax.

So what's the difference between the -6 and what I have now? Will the wheel stick out further or not?

how wide are the rims you're now looking at?

the numbers for offset are in millimeters... think about it. 1.5" = 38.1 mm-25 for your stockers = (-)13.1 mm now. versus -6 if the new rims are the same width.

The rims are Raceline Raptor 18X9 6X139.7 -6 offset. Not planning on running spidertrax. The other offsets are 12 and 25 I believe.

so the -6 will be in towards the fender wells 7 mm more than they are now. BUT, it won't be noticeable at all since it's a wider rim than your current stocks! Do itt, that's perfect man.

 

[knightsfs4]

So it will be 7mm further out? You're right, that's pretty damn perfect. Got lucky here I guess if you're right!!

i think 7mm more in, not out since its currently at -13 with stockers and spidertrax. The rims will be -6, which brings it back into the wheel well 7 mm, but since it's an 8" rim instead of 7.5, it'll even it out perfectly. And even then, the 7mm visibility is not even noticeable

Here is how I see it. If my guess on the 25mm offset is correct, the -6mm offset wheel's centerline will be almost the same as your factory wheel with Spidertax. The rim itself is 9" wide as compared to 7.5" so the edge of the rim will stick out .75" further on the outside and also .75" further on the inwards compared to the stock ones. The tire is centered on the rim so the center of the tire should be in about the same position and the outer edge of the tread portion of the tire shouldn't stick out much more, but the inner portion (bead) of the tire will stick out .75" more and the side wall of the tire will probably stick out more (less than .75"). Hope this make sense.

all that to say that the -6 will be the perfect offset.eace:

Pretty much... lol. I have been considering these Raptor wheels and I am trying to decide between the 17's with the zero offset or the 18's with -6 or +12. The 17's have the perfect offset for me but I was kinda hoping to get 18's. Someday I will make a decision!

please, educate.

get your dremel ready to do some trimming.

it can be done, but not without issue.
