1.6 3 door dynamic, upgraded alloys from 16" to 17"

About a month ago I upgraded my alloys to the 17" abarth 5 spoke type, with nearly new continentals, from the standard 16". Almost immediatly I noticed at 50-60mph the whole car starts to shake as if the wheels are seriously out of balance. I have had all 4 wheels balanced but it still shakes at 50-60mph, from 0-50 and 60+ it's fine:confused: Yeasterday I noted a further speciality. The shake only occurs when I am accelerating, hold the Stilo at 55 and it's not even noticeable go up to 60 and for the duration the engine's working harder it starts to shake!

Any ideas???

its a wheel balance problem, had this on mine, on the third attempt of balancing the front wheels it disappeared, the weights came off on the 2nd balance after about 100 miles!
