If you are going to change tire size and then trying to use the odometer or speedo (w/o recalibration) is silly.
You have to calibrate for the difference in doing the math for mileage.

All of my posts concerning larger diameter tires are based on:
1. Garmin gps for true mileage
2. calibrated ScangaugeII
note: SGII is calibrated in the metric mode w/ gps in the metric mode. this gives a more accurate reading when switched back to miles.
MetroMPG: "Get the MPG gauge - it turns driving into a fuel & money saving game."

First: ScangaugeII

Second: Grille Block

Third: Full underbelly pan

Fourth: rear skirts and 30.4mpg on trip!
