Front Tire Cupping / Alignment (?)
I have 20K miles on the second set of Goodyear Eagles and just noticed that the front tires are cupping / scalloping inboard side of the tires. I'm having it aligned next week at the GM dealer. The original tires were replaced due to a lateral imbalance by GM. Is the factory recommended camber to aggressive? If so, I suspect that one could only expect approx 20K miles and then be faced with the cost of replacement tires. If the camber is indeed too agressive, what would your recommendations be.
I'm just a daily driver with occasional spirited driving. Not really doing any racing, etc. If I were to change the camber to eliminate the tire cupping, is there other alignment specs that would also have to be changed, as in castor?
Thank you in advance for your help and recommendations.

May also be signs of suspension issues. I Have not had my car aligned since I bought it four years ago and the EMT's that were on it wore evenly down to nothing. My current GSD3’s have been on two years and still have even wear.

There is no way that camber setting can cause cupping. If the camber is too aggressive it will cause wear on either the inside or outside edge of the tire but it will be even wear throughout the diameter of the tire.
Cupping is most commonly caused by worn suspension components. Before having an alignment done I would have the complete suspension system thoroughly inspected. Do not assume the alignment shop will do this without being told.
There are two different factory camber specifications; one for the Z06 and one for non Z06. While the Z06 settings are more aggressive neither is too aggressive for street driving.

After you take care of the suspension part issue, have the camber set as close to -0- as they can. That will reduce your inside wear.
