I have a Question I am really baffled by. I am looking at a set of Fuel Beast wheels to put on my 2015 Sierra . I already have a Rough Country 2.5" level kit on my truck. I want to get a set of BFG AT K02 tires as well. the wheels I am looking at are the 20x10 -18 offset . what's the biggest tire I can get on these without rubbing . I was thinking of 25/65r20's or 295/60r20's but i'm not sure if that's too much sidewall or not for just a 2.5" lift/level. Has anyone done this or have any input. I was hoping the -18 offset would allow me to run these .My end game plan is to run a 6" Fabtech or BDS lift but I just want something to hold me over a year or so till I can scrounge up the extra cash.
Any info on this would be greatly Appreciated.
