This depends on so many variables, there is no right answer. Your car setup and driving style will determine your preference. I like running 18X10 and 275/35 all around, both because of handling balance and freedom of 4 wheel rotation. I have never seen the wisdom of running staggered wheels/tires on a front engine/rear drive car with neutral weight distribution. But that's just me.
