I'm trying to tune in my speedo due to new tires. Does anyone know which tires the speedo uses to measure speed? My front and rear tires are different sizes and I don't know whether to adjust the error according to the front or the rear. Any help would be appreciated.

 

stock tire size is 245/50R16. It uses the rear tires.

Thanks Brian!

 

Speed is measured by the VSS (Vehicle Speed Sensor), located on the tailshaft of the transmission. Yea, so rear tires.
