Home again

My odometer says I just finished 9,516 miles, but the GPS trip meter says 9,634 miles, and I set them at the same time. Personally, I trust the GPS. Every since I got new tires, the speedometer has read low. If the needle says 60, the GPS reads a point or two higher. It makes sense. New tires have a greater circumference than the old ones. More inches per revolution that the speedometer has no way of knowing about. Actually, I had expected more of a difference. Maybe since the tires are now ten thousand miles older, it's evening out. I suspect it's the older two tires, the ones that I had rotated to the rear that make the difference.

That's a lot of miles! This is exactly something I would spend my time thinking about. Glad we have that in common. So glad you enjoyed your trip too.

Good to know that your GPS seems to be pretty accurate like you think it should be, too.

It sounds like you had a great trip!
