I tried to read every flipping thread and pic online to find this answer before I asked but came up short with an answer so here goes.. I have a 2019 Ram 1500 Bighorn no lift no level no air bone stock and question is can I fit a 285/60r20 or 285/65r20 on a zero offset 9/20 rim ? I'd like to go with the biggest that will fit. I don't mind trimming a little plastic. Thanks for anyones help on this..
