Can somebody post the minimum and maximum range for changing tire sizes on the MM3 on a 4th gen? I needed tires in a podunk town and ended up with a smaller than stock tire size and when loaded, the speedometer reads way high. Once they need to be replaced, I will swap them out for a larger size. I was planning on a tuner soon anyway, so if this can keep my navigator from thinking we're speeding all over the place, then even better. Thanks.
