Hello
Just bought a 2013 Ram 1500 sport 4x4, I put a levelling kit in the front and pocket style bush wacker fender flares.
I am looking to swap out the 20 inch rims for some aftermarket 17 inch rims and 33s.
Does anyone know how to determine the proper offset and backspacing so the new rims and tires stick out 2 inches or so more then stock, so they are flush with fender flares?
I've been told i need a negative offset, but i am not sure how to determine how much offset i need?

Any help would be appreciated.

Thanks in advance.

 

Wow no response? How'd you make out?

 

Everything needed is in this thread here:

4th Gen is the same as 3rd Gen.backspacing is nearly identical . difference of 0.05mm on the factory rims. that's half of a millimeter.
