I run 225's all around and it's not that bad. Was in a rush and that's all the tire shop had at the time; 225/245 would probably be better but the car is by no means a nasty handler. Oh, but I do have a big front swaybar.
Then again I must not be a very aggressive driver as I got an average of 18.5k on two sets of rear S02s...

JZR provides a good example of just how much "driving style" reflects in not only tire wear, but an honest assessment of what one "requires" when pursuing aftermarket tire/wheel combos. There are those who can get 15K on S0-2's and those who can't get past 6K on 'em. A 225 Kumho is an "ok" choice for someone who simply doesn't push the car. What does "push" the car mean?
* Doubling exit/onramp speed limits might qualify.
* Driving the same in the wet as you would in the dry.
* Lightning quick lane changes when a simple turn in would do.
* Heel/toe driving at every opportunity.
The needs of someone who drives aggressively (following the above examples) would need tires staggered appropriately. The only exclusion to that would be a very experienced sportscar driver with not only years behind the wheel of assorted rear wheel drived autos but a few driving schools under one's belt (I offer myself as an example). Pronounced oversteer to them isn't a four-letter word. In my case, when pursuing same-sized tires on a mid-engined sportscar that even when tire-staggered FROM THE FACTORY, is known for sending folks into the weeds (MR2-Spyder) then a 205/225 Escta combo on an S2000 is a breeze to control (though not nearly as much fun to drive...I'll admit, I'm a mid-engined guy). Anyways, I haven't lost control of my car once since putting them on at 1K and I've got 8700 on the odo. However, I know I'm in the minority so getting back to the general rule of thumb. Boulevard cruiser bent on stylin'?
A 205/225 combo would be fine. For most everyone else, using your chosen wheel specs (size, width of rim, etc) as a guide, always try and get as much stagger as you can.
One more thing. For every .5 inches of wheel width either added of subtracted from the measuring width of the wheel a tire was spec'd on, you can adjust the tread width 5mm (or .2 inches). The S0-2 provides a wonderful example. The measuring width of the wheel used to spec the S0-2 rear was 7-inches. As a result of placing that 225/50/16 on a Honda 7.5-inch wheel, the tread width (normally 8.5-inches) increased to 8.7-inches. Many of BF Goodrich's 225/50/16 tires are notoriously low for tread width and depending on the wheels used, can nearly be an inch (or more than an inch) narrower than the S0-2 225/50/16 spec'd for the S2000.
I have seen 245's that are narrower. The Sumitomo HTRZ has a decent sized tread width compared to other like-sized tires and so does the new Yokohama EVS100. Most other 225/50/16 tires are in the 7.7 to 8.1-inch range.
