Using the tire size calculator here: http://www.miata.net/garage/tirecalc.html
The diameter of the tire goes from 24.1" on the 50 series, and 24.9" on the 55 series tire. So you'll end up with .8" bigger wheel diameter.. you'll have to look at how much clearance you have in your wheel wells.
I'm running a 195/65/15 winter tire when the stock size is 195/60/15, and I'm lowered on FK 35-40mm springs (about 1.5") and haven't had any problems. There's a little less wheel gap but I haven't had any trouble. It might be more of a pain if you get a lot of ice buildup in your wheel wells, really depends on the type of snow/ice you're driving in and the temperature.
