For modern radial tires I agree to a point. I remember the fiasco with the early Firestone 500 steel belted radials (among others) that had belt migration problems. Regardless of what the book said to set the toe, we used 0 or 1/32" toe in to help keep those belts from coming out the sidewall. Having 1/2 degree of negative camber isn't even visually noticeable IMO, but helps in cornering and emergency handling.
I agree and I almost consider that positive it's such a small amount. The Firestones were nothin but POS tires right off the bat. I've seen them separate literally sitting on the storage shelves....even come on on the truck already separated.
