I have a 2012 Ram 1500 Sport 4WD with a 6" Rough Country Suspension Lift Kit Running 35x12.50R20 Toyo M/Ts. I am looking into buying 20x12 -51 Offset wheels. I'm wondering if I can clear these wheels on 35s, does anybody have a similar setup? This is what My truck currently looks like.

 

How wide are your current wheels? and what backspacing? I *think* backspacing on the 20X12's is going to be right around 4 inches.....

 

Current wheels are 20x9, but I have a 1.5" spacer. Would they stick out the same without spacer? New wheels backspace would be 4".

 

Then yes, they will likely stick out a couple inches further. What's backspacing (with spacers) on the current wheels?

 

Stock rims should be centered. Backspacing would've been 4.5" but with spacer it's 3" I think.

 

So, you have wheels 3 inches wider, and are going to end up with an inch more backspacing, so, they will sit about 2" further out than the current wheels do.

Or something like that.... I sometimes get the directions confused. Comes from being old.

 

Yes 1" more backspacing compared to stock and 2" more sticking out.

 

Works for me.
