Default Re: Speedometer 4-5 miles per hour under actual speed
FWIW - I just verified my Speedometer reading this AM via independant GPS (Garmin GPS-V) at a couple of speeds;


30mph indicated - 28mph GPS
40mph indicated - 37mph GPS

I have not yet been on the freeway with the Garmin in in the car. BTW - it was registering 7 satellites most of the time.

So - it would appear that our fuel economy figures would be inflated as well.

When I buy my new 17 or 18 inch wheels for summer, I will run a slightly larger (diameter) tire to help make up for the error.

.
