I'm up for new tyres on my Ghibli. Currently it runs near new Dunlop SP SPORT 9000 215/45 ZR17 on the front and old (need replacing) Pirelli P ZERO ZR 17. I have only just purchased the car and plan on no track days at the moment (but will after June). What do you run on your road and some times track car?
