Look at the side of the rim of the wheel IIRC Punto GT wheels are stamped ET45 so way incorrect for a Cinq. So you need to run 20mm spacers at front and 10mm spacers at rear otherwise the track is far to narrow on the car, the reason the car doesn't move is the wheels are probably hitting off the struts or other suspension components, best size of tyre to go for is a 185/50 15.
Of course like most things on here it has been covered many many times and all the naswers you need ar on here already if you bothered to search or even read the information stamped on the wheel.
