Spare Tire Question

[Casey]

Bringing this back up. Won't different size tires cause problems with the TCS trying to kick in? I remember a recent thread that when the wheel speed sensor was lost, the TCS kicked in and I think fixes were discussed to prevent false triggering on that event. I can see where this could cause similar problems.

In any all-wheel-drive vehicle, you really want all wheels sized the same.

Anyone here try running an odd sized spare that can comment?
