Actually, it's more to do with the tyre wear. The outside wheels are becoming more worn, so the they are producing less grip than the inside wheels. This results in the vehicle veering slightly towards the inside of a corner. It's why they usually only ever change the outside wheels in NASCAR racing - they're the ones that suffer the most stress.
