To be honest you'd be better fitting a 185/50/15 to stop the speedo reading being illegal!
The law dictates that a speedometer must NOT read UNDER but may read OVER by up to 10%
The 195/50/15 tyre would make the speedo read under by 3.5%.
A 185/50/15 tyre will still read under but by only 1.7%
Ideally a 50 series tyre would have to have a width of 175 to be totally within the law.
Having said all that of course, I doubt whether speedo accuracy is going to be the main thing plod would be checking on a 100HP driven in anger in winter!
you're forgetting the speedo isn't 100% accurate to begin with. cars normally leave the factory with the speedo reading a couple of mph under the actual speed to allow for changes to tyre's, wheels and to cover their own arses.
there's more than 1 recommended tyre size in the handbook.
