issue with Porsche 914 speedo readings

Hi All
i have a porsche 914 speedometer, it is in KMPH , front tires are
205-45-17 and compared with a gps and my friendīs car , the speed reads 10 kilometers higher that real , if speedo marks 100 km, i am really running at 90 kmph , any options to solve this ?
i think changing to a bigger profile on the front tires, but i am not sure, and dont want to end up with a big 4x4 tire...

any clues or thoughts are welcome
thanks !!
