Have you checked your ride height?
Tops tilted in is negative camber. Not always adjustable that much, usually it's an eccentric bolt, but I would think that wear would move it even less, unless you have some really extreme slop. Haven't looked to see how it's done on an LR. But on most vehicles, lowering will cause negative camber, raising positive. I would think with the large range of travel on the LR suspension this effect would be minimized, but something to consider. Cutting coils to lower compact cars is one reason why their tires are tilted in at top.
