Getting ready to send our Series V speedometer to Nisonger for custom calibration. Using the "Push Test" we measured 1375 turns per mile (TPM) on 165-75x13 tires and 3.89 differential. Lettering on the speedometer shows 1042 TPM. In use the speedo indicates 3.4 miles over a measured 2.4 mile route, and indicates 60 mph at what seems to be ~40 mph. We think we have consistent results because dividing the larger TPM, distance, and speed by the smaller yields errors ranging from ~30% to ~50%.
