July 13, 2010 odometer 125434
- had 6 new tires (Firestone Transforce HT) installed at Paducah Tire 235/85R16E replacing the original 225/75R16E. I went to a larger tire to effectively change the final gear ratio in the hopes of increasing MPG. Speedometer reading of 60 MPH on new tires roughly equal to 65 MPH in reality. Odometer correction factor: reading*1.06=actual distance. New tires cost $844.80 installed complete.
