Not sure how long it was on the lot. The rear tires were over inflated by 10 pounds according to service and they re-balanced the tires. Still didn’t fix the problem. Taking it in on Friday morning to get looked at.How long was it on the lot for? My daughters car was parked for long periods of time while away at college and the flat spots and vibrations did go away. Ideally the tires should have extra air while stored to eliminate that from occurring. Hope it gets straightened out quickly.
