I went on a trip from VA to SC and when I was down there, i rotated the tires. The car had about 9k miles. I started to notice that the front end felt a lot more sensitive to the road conditions and bumps. It feels like I just got a big case of bumpsteer. I re-checked the lugs and I don't think the belts are out on the tires. Could this be due to the almost non existant tread or is this just common aging of the car?
