From our earlier conversation on this, I made some observations on the way home from Fernley and would be interested to see what other people in other cars get in the real world vs. what the specs say they are.

Everything is rounded to as close as I could get/estimate and hold for some time in a straight line on cruise.

Code:

Car: '04 STI
Wheels: 17x8 RPF1s
Tires: 225/45/17 RE070s
Gear RPM  Speedo GPS Speed
6th  2750  70       66
6th  2900  75       70
6th  3100  80       75

Speedometer error is pretty interesting considering these are the OEM tires on only slightly wider wheels.
