You are going the wrong way as the sweet spots (IF THERE IS ONE) is at less than 1550, not the 1800 it's probably turning. Even going with a 315/80/22.5 is not going to gain you enough. STOP looking at the Panther with the CAT engine as the 5.5 is all you'll get out of a C13 and find the same MH with a Cummins or Detroit and it's called a Monaco Exe that will get 7+ mpg. As I posted previously, my Aladdin system is very accurate and unfortunately 5.5 is NORMAL for a Acert C13..
