The tires may deflect more on the inner edge, but they certainly don't have any more load on them.

I disagree but I think we're talking about 2 different things. I'm talking about pressure against the ground, not air pressure in the tire. More pressure against the ground on the inside of the tire b/c/o camber equals faster tire wear at that site. Shaving the tire consistent with the camber angle would place equal pressure across the entire tread which would allow the tire to wear evenly.
Racers do shave their tires for a several reasons. A few are for the same reason I mentioned in the previous paragraph to promote even tire wear in negative camber suspension setups for longer tire life and for better traction, even pressure against the ground across the tread.
I'm looking into it solely for the purpose of extending tire life. Replacing rear tires every 14-15K at $500 a set is bordering rediculous. I already spend enough money replacing prematurely failing parts on the X as it is. I have already straightened up the rear tires as much as BMW will let me and still inside wear. Shaving might be worth a try . . . it can't be any worse.
