No BS: Lifted and big tires, real mpg?

I actually downsized to 265/75s when my tires needed to be changed, changed to P-rated less aggressive and lighter tires, and have been happier with look and ride, and my MPG’s have gone up about 1 MPG on flat highways at 65 MPH. I changed because I needed new tires and they were less expensive. Truck has 1.5 lift also with Bilstein 5100s. I recently added OTT tune and MPGs around town have been stable between 19 and 20 on average, with some hills and traffic. A few miles per gallon either way don’t really matter in the bigger scheme of things as there’s too many variables to include wind, pavement, and my heavy foot.

 

285s here, 2/1 Bilstein 5100s with KDMAX tune and a in line RC calibrator. I then added the TRD Pro exhaust and TRD CAI box for looks. I get between 18 and 19 around town, with some back road driving.
