I was asking my self the same questions when i was deciding to increase to a 265 from a 255.

I went from Bridgestone (255 30 19) run flats to michelin pilot sports (265 30 19)

The diffrence was incredible.

But anyway here is a online tool I used to compare the different tyre sizes and how much your speedo will be out at a given speed.

Hope it helps
