lets see here... 18x8 +30mm and 18x7.5 +35mm....
according to my calculations with my handy dandy scientific-mathmatic device... the 7.5 inch rim is narrower. also with the same calculator i have determined the +35 has more of an offset than the +30 rim.
I'd speculate that by logical reasoning backed up by scientific calculations if the wider, less off-set wheel tucks, then the narrower, more off-set wheel will also tuck, providing the track widths are the same, or the latter is slightly wider
i'd also speculate that i'm an ass hole.
