Did you ever ...
... measure your vehicle against one of those "Measured Miles" on the Interstate or the turnpike? In every vehicle I've owned for 30 years, the speedometer has always indicated 5% more distance than I traveled (1.05 miles) and the speedometer, of course, 5% faster than I was actually going. I don't actually know that this is a conspiracy by the automakers to make my car feel SPEEDY, but it has been remarkably consistent. Putting on larger tires should bring it back toward reality, by making it actually go farther per wheel revolution, and therefore actually go faster, without changing the odo/speedo readings. If I have all that worked out right.
