Tire Size

I have a 98 Honda Accord EX, the factory specification for the size of my tires is 195...but I recently bought brand new pair of tires and noticed that they are 205s. I am thinking about buying two more but which size should I get the 195s or 205s and does it make it difference?

just my opinion, but i think that if your gonna get 2 more tires than get them the same size.

I mean..that way you won't go through them faster, because you can still rotate all 4 of them, and not just rotate 2 every so often...that is if you do rotate your tires.
