Average is probably just shy of 17 mpg. And on long road trips I can get as high as 21 mpg, but not much more than that.
Overall a ~1.5 to 2 mpg drop from my non-Sasquatch factory setup.
EDIT— Also… this is all calculated from fuel receipts rather than relying on the vehicle’s computer. And I did recalibrate the speedometer after installing the new tires.
