I don't understand it either, but there have been enough reports of problems that it shouldn't be discounted. My guess is that the vehicle is measuring ground speed and comparing that to wheel speed. If it sees a difference, the electronics assume the vehicle is skidding.

I'm hoping you realize that there isn't an answer to your question as the issue is complicated and varies all over the lot. There are factors that have much more impact than tire size - and the difference due to tire size isn't consistent.
