You need to plug in 305/30/20, as the speedometer reads from the rear tires on a Mustang.
I think the point was that you used front-tire-size to get your 1-mph-difference estimate, when you should have plugged in your rear tire size instead.I don’t get what you are saying? I really don’t care about the speedometer as I go as fast as I care. What is the question?
You may not care about the speedometer, but that is what you are using to get your estimate.
