Hello, I have a 2007 ram 2x4 with 33x12.5 tires on 20" wheels with a zero offset and a 2" spacer, I like the stance now (amount of tire sticking out of wheel-well) . But I want to get rid of the spacers so what size new wheel and offset should I buy to keep the same amount of tires sticking out, same stance basically I do not know if i am asking this the right way sorry. thanks

Offset
For your current wheel width and diameter with your Current Offset at zero minus the 2" spacer (approx. 50mm) = "negative" 50mm offset, I do believe.

Backspace
Pull the wheel off measure the current backspace and subtract the spacer thickness. If it's 4-1/2" subtract 2" = 2-1/2"backspace.
