I am astounded that a Volvo dealership would fit cheap chinky ditchfinders.... just to check they are "Royal Performance" not "Uniroyal" ??

Shame on them - I don't rate your chance of getting any contribution from them but they should enjoy some harsh feedback from you. I would ask that they fit new Pirelli's at cost?

Generally there is no such thing as a cheap tyre - some are better value than others but none are cheap.
