Front tires wearing on outer edge

I pick two points on the tread and hold the tape as high as I can go without it bending. 1/32" toe in this way is 1/16" measured the correct way. Also, since the tread isn't perfect, one should run a line along the tire tread by spinning it and marking it, and not disturbing the line while you settle the suspension. I can get more accurate results setting caster, camber, and toe with my tape measure, square, and machinist scale than places with their $50,000 racks and $10/hr. experts.
