Running a 2015 jk with 2.5 lift and black rhino sprocket 17”rims -18 offset 4.5 backspace. Need to get new tires and want to upgrade to BF Goodrich 35 KM3. My question is can I do this with the oem tire carrier or do I need to beef it up? Will eventually change out rear bumper to one with built in tire carrier but one step at a time. Any other issues I may not be thinking about as well?
