Wheel backspacing

[canders13247]

I just got another Ram and I'm going to lift it in the spring. I'm doing a 2.5" spacer, 2" block and adjustable track bar. I was wondering what backspacing I would need to fit 33x12.50s?

Anyone! I have searched and searched and now luck on a definitive answer.

i was running 33/12.5 on my stock dodge rims. im not sure how much backspacing they have but i hope this helps. They did rub when fully turned hard, but not to much

You're gonna need 9" wide wheels in the diameter of your choice for 12.5's. Stock rims arent wide enough, wont wear right. Not sure on back spacing or offset though.

I was taught that the wheel should be no less than 4" narrower than the tire. Everyone runs 12.50s with 8" wheels, so I'm going to be getting those in 15" diameter.

Where they 16" wheels with 285/75r16s? If so those are only 11.5(ish) inches wide. I can't find ANYTHING on backspacing. So I have just been looking up pictures of trucks with certain things. I've decided on 15x8 wagon wheels with 4" of backspacing. Should have the lift and tires on by the end of this month.
