    What tires are you using? As in brand and specific model. There is a table somewhere that has how many revolutions per mile it will take. No need for the height.

    I dont keep the truck here, I know they are new Michelins. I figured it out in the chart above, tire size varying an inch either way only made a difference of about 2mph.

    Its for transporting campers, 2 @ 3500-4500 lbs . One on top and towing one behind.
    Might be a bit more, Other trucks like it are registered at 36k for hauling heavier vehicles back. I am still working on it but guesstimated empty weight should be around 22k,
