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.
I've never looked to see the full range, but the tuner should allow correction for any tire setup you can fit.Originally Posted by 50Devastator
