Hey Guys, I have a 2007 Saab 9-3 Aero. In my brochure it says I'm supposedly suppose to have Pirelli P Zer0 Tires on my car, but it came with Continental's? It didn't take long for them to wear out. This was an expensive car. Does anyone know if they are suppose to come stock with Pirelli's on the Aero package? Why would they put such cheap tires on an expensive car. Thanks
