Re: JK Sahara 18x7.5 255/70/18 fitment
Pretty sure the Sahara wheels will fit, but it's not for certain.
I know specifically of another member here who posted photos after he got his installed (not a 2014, but still WK2) and he had about a centimeters worth of space before they hit the calipers. They still worked for him though.
*Search "Sahara" in the WK2 section. Quite a few people have them mounted. FYI
