My theories:

1. The worn tires and good tires have different diameters throwing off the system.

2. As the previous poster noted, the worn tires have more (or less) grip and causes imbalance.

I did not have the issue before rotation.
I'd agree with both theories. A combination of the above contributes to DSC stepping too soon.
