I'll agree on the feathering. I'm splitting hairs I guess. The picture is just old school and looks like a biased tire that just feathered a couple ribs when the toe was off just a little compared to scrubbing the whole tire when toe is off by a large amount while a radial tire will flex the sidewall, when toe is off by a small amount and push the whole tread over and just scrub the edge. Inside when toed out and outside when toed in. Comparatively, camber will wear more of the tire than just the edge. It's a fine line to decipher but the numbers tells the rest of the story.
