Within 3 mos of owning my new 20 Limited I noticed tire scuffing on the inside of the front tires. Early on in my career I did front end alignments so it was obvious to me it was either negative camber or toed out. It also wandered and took small corrections to the wheel all the time to keep it straight. I took it to the dealership who took it to the local tire shop. I told them I would like camber and toe, front and rear set as close to zero as possible, which they did. The alignment man told me the rest was tied out and the front had lots of negative camber, which in theory can make the car handle better in the corners. From what I have read this could be true. I felt like the Ascent handled well but I drive it slowly through corners so losing a little did not matter to me. He told me the tires should wear well now and the wandering should be less noticeable. He was right. I did not notice any difference in handling and the car drove fantastic. My first set of Falkens went 43k, I think they would have done a little better if they weren't worn initially. I feel these settings are excellent for smooth operation and good tire wear.
So to answer your question, it sounds like your problem is close to what I was experiencing with my tire wear. Do you have a copy of the before and after alignment specs? Look at it and see how the camber and toe are set. As close to zero on both should get you good tire wear. After that, keep watching your tires for unusual wear, keep them inflated and rotated. If you are seeing wear or having driveability issues with wandering or pulling, get it in and have it checked! Beats losing a set of tires or wearing you out trying to keep the car straight in the lane. I hope you get it resolved soon. Nick
