I have had Conti DW performance summer tires on my TDI for over a year, now, and run them between 40 - 41 psi. For me, that is a good compromise between handling and comfort, and gives the added benefits of longer tire life and better fuel economy. Note, however, that the standard sport suspension on the US TDI, while about equal in handling to the GTI on real roads, is a bit softer and more forgiving on bad roads. Also, 16" wheels help and are better suited to the chassis than 17" wheels.
Pros: good handling, good comfort, longer tire life, better fuel economy
Vehicle:
Volkswagen
