The Methods with 25+offset on 275/70-18 dont rub. Its basically an additional 5mm more offset than your stock wheels with the +30mm bora spacers.
Mounting a KO2 275/70-18 on a 9” wheel is 1/2” over recommended section width (7-8.5”) and the tire flattens out nominally so youll be squaring up the tire a bit. The optimal section width on the 9” wheels would 8”-10” like a 285/65-18- slightly less tall (-3/8~1/2” depending on brand) but wider and tad better protection for the rim.
