Sorry if this is already posted somewhere, but I can't find it. I know you can put 15" rims on a JK with the correct backspacing. My question revolves around the hub. I am looking at some wheels that are 15x10 with 3.75 backspacing. I know from what I have found on the forum that this should be adequate. They are 5x5 (5 on 127) bolt pattern. The hub bore is 83.06. I am not having a lot of luck definitively finding any information on this. Can anyone school me in the hub bore size necessary for a jk? I've seen people list sizes from the low 70s to the high 80s both here and on other forums. Thanks in advance.
