I've been thinking about that all day. I thought the same thing... I still do. Smaller tires would have to spin faster to go a given speed. Larger tires would spin slower to go the same given speed. The truck would think it's going slower than it is and the mileage should add up slower. I'd have the speedometer calibrated to address this issue.That doesn't make sense, larger tires will make the odo show less than it should not more.....
