Wear on the outside edges isn't caused so much by toe or camber, as by cornering, With the weight of your X5, it takes a lot of force to change direction, all of which is being transmitted through your front tires and thier slip angles. If you lived in Wyoming and drove arrow straight for hundreds of miles at a time, you'd see much less wear. If you ran the Tail of the Dragon every week, did HPDE's or autocrosses, you see accelerated wear.

If it makes you feel any better, 23,000 miles is pretty darn good. I wish my Dunlops would wear that long. Did you consider going to a non-RFT like the Conti DWS's? Much nicer ride, and a significant savings. Lower weight will result in less unsprung mass and less rotational inertia, which will improve the handling when you do run the Tail of the Dragon.

BTW I'd spring for the TPMS rebuild kits. YMMV
