General HELP! Just bought alloys with 195/45/R16 tyres
You just answered your own question then, if the rolling radius is different the speedo will be out and they might well clip the arches too on full lock.
Yes your speedo will be knocked out of accuracy.
Because the rolling radius is smaller that what the speedo was calibrated for it will think you are going quicker than you are.
Best thing to do is get rid of the tires and get 195/45's put on. Im in the process of looking for 195/45 R16's now for my 500 alloys
If you dont fancy doing that you can also get your speedo re-calibrated. the cheapest way of doing it is driving with a satnav with speed indication or go past on of those Street signs which show your speed. that will show you the percentage that your speed is out to the indicated speed

dont see why they would clip the arches...
195/45/16 will fit fine without clipping (depending on offset)
195/40/16 have a smaller profile so less rubber meaning less to clip the arches than the 195/45
I was typing in a rush and thought they were bigger profile rather than smaller

No worries, was slightly confussed by that post. but that makes sense now
Your speedo will read fast and the car will accelerate quicker as 195/45R16 is roughly the right radius for these cars
