I'm using 205/50R16s and it's fine.
it just really throws off your speedo and odo. See link below for by how much:
http://www.miata.net/garage/tirecalcold.htmlthe 205/50 R16 is closer to the stock tire size than the 205/50 R15.
With my 205/50 R15's my speed might say 140, but I'm really only going 135

That said... I found some Falken Ziex's in 195/55 R15 .. but they only have 2... going to take the 2 for now (as my fronts are critical)... and look around for the other two
