will I need (should I get) wheel spacers?

Ok, I am sure the will it fit and will it rub have been done to death.

I have a real hard time understanding offset and backspacing. even with the websites that show me how much different back spacing and offset will affect how the wheel sits.

So anyways, I have a 2013, currently on 18x9 methods, +18 offset with 35x12.5x18 nittos

I have 6112 bilsteins, top setting, SPC control arms and a body mount chop done, no noticeable rubbing except a little paint rubbing on sway bar, very slight. I do have a high clearance front bumper

I am going to factory rock warriors, want to keep the same tires, 35x12.5x17 but I know they are plus 50 offset, so that will bring the face of the wheel outwards but the inside closer to the body.

So would that mean more rubbing on sway bar and possibly control arm clearance issues?

I have researched the difference in offset would be about 1.29" so would a 1.25 or 1.5" spacer fix this potential problem.

I am asking because I would rather have a solid answer and buy them ready to go when I get around to swapping wheels, rather than needing them and not having them handy.

 

Going from 18mm offset to 50mm is a 32mm change. It will move your tire in a little over an inch and a quarter. See image below.




So go to your truck, crank it full lock (have somebody in it to hold it at full lock), and then measure all points of both tires and where they will be if they move inward 1.26 inches. Then turn the other direction and repeat. It's not perfect, but it will give you an idea of how your clearances will change.
