I know of one exception to this - the rear tires on several GM models will see severe wear on the inner shoulder under the stock alignment. The most prominent models for this were some recent W-platform (Impala, Grand Prix, etc.) vehicles. They set the rear camber so severely (3 degrees if I remember correctly) on these vehicles that you can see it when you're driving behind an unmodified vehicle. I had a set of Firestones on my Grand Prix that were pretty much junk after being left on the rear of the vehicle for 15,000 miles (after 23,000 total miles on a 55,000 mile tire) because the inner shoulder was so badly cupped (front tires easily had another 35,000 left in them). Ever since, I have my tire guy install a camber bolt kit when installing my first set of tires to bring them back within a degree of vertical.
From what I have seen of our Cruze (at least my Diesel), it looks like GM used a similar rear camber setup. If anyone has had their Cruze on an alignment rig and seen the rear camber numbers, I would like to see what they are stock (maybe I'll start another thread for that), but to me it looks like they're at least 2 degrees, and maybe more. I guess I don't mind, because it will help me burn through these OEM Goodyears faster so I can put a better tire on next fall, but when I do it looks like a camber bolt kit is in my future again.
