I took the '99 in to get the tires balanced this afternoon. The girl called me to say it's ready and that the tech said the tires are chopped, so they may still have some vibration. WTF? I asked to speak to him but she said he was at lunch. What does this mean, and what should I look for when I go to pick it up? I don't think it's alignment, it tracks fine. She said I can talk to him when I go pick it up.
