Like the others posted above, toe is what will wear out the inside of a tire fast. Camber does little.

You actually didn't gain much camber in front from lowering it due to the Macpherson struts.

I'm actually surprised that you added positive camber after lowering your car. Why did you do that? Zeroing out the toe would have decreased inner tire wear significantly while maximizing negative camber would benefit handling with negligible tire wear.
