I am looking at the Moto Metal 961. I have thought about 18x9 but it has a 18mm offset(5.7" backspace) so I think I should go with the 18x10 which has a -24mm offset (4.55" backspace). I want the tires to reach the outer edge of the fender. What size tires do you have on those 18x10's? how far do they sit from the edge of the fender?
