I had a F350 srw with 275/65 R20 BF Goodrich KO2. I had them on XD wheels. I plan on putting those tires with 4K miles on the back of dually and getting two new tires for front. (Wheels will be for sale) The offset was 40mm more than stock.

I am looking at 20”x7.5” American Eagle because of width. (Other if dont stick out more but i am lost) I do not want the wheel/tire to sick out more than 1.5”. I dont think i need spacer. Anyone have pics or advice? Thanks a ton.
