Yes, high reported MPG figures by some may be due to this type of error.
I wonder if you can give us 2 pieces of info. First, what is the
complete exact size of your left front tire? Second, what is the small
number printed on the dial of your speedometer face near the center?

I suspect that these 2 pieces of info will explain the error.
