I just bought a 2005 g35 coupe and the origianl 19' rays were beat up badly, so I bought some 19" 9.5 wheels all around and I have no clue what size tires to run. I don't like super low profile look and I do drive far to work, so I need as much meat on it without it looking stupid. My C6 vette has 285 30 19 in the rear and 275 35 19 in the front, seems very similar, but anyways thanks for looking.Have a good day.
