Stock is 215/70/15ish. So unless the PO corrected the speedo which I don't believe he did by driving it, I've corrected the numbers myself. I filled up and it was 13.6MPG, should hit 14-15 with ODIs your speedometer correct? I'm not sure if 31's are a stock size for those trucks. Mine is off, if I forget to add the correction in for the tires, it looks like I'm only getting about 9 mpg.
good man. what year?
