As Stephen said, the Prodrive settings from what I was told a while ago, have more negative camber. Since the tops of the wheels are tilted in more, then the lower inner-edge of the wheel is more in contact with the road causing that part to wear faster. When I replaced my tyres a few months back they were pretty much wedge-shaped, some tread left on the outer part of the tyre gradually going down to almost nothing on the insides! This is what I mean by OTT IMO. Tyres are an expensive consumable, so for me, it is better to use settings that are a bit more tame thus making them last longer. As far as I can see, my tyres are currently wearing more evenly across the tread. I don't have a copy of the printout though, I lost them when I moved house so I don't know the differences in the camber settings.
