The guys on the G35 forums are saying the closest to stock is 245/35/19f and 275/35/19r but not on OEM 19" rims, only on rims that are at least 9"....
That's why i was wondering if i went from 225/40/18 (my current incorrect tyre) at the front, and wanted to get a 19" wheel+rim, then apparently the correct is 245/35/19f and 275/35/19r, and my question was - this actually lowers the ride height?
