    We're not looking at the effect. but the change in the effect with changes in mass. A 20% change in mass increases the driving force from gravity by 20% and also increases the retarding force from...

    How is ignoring rolling resistance splitting hairs? There are two terms in the equation of motion that scale with mass: 1) the driving force due to gravity, and 2) the retarding force due to rolling...

    Ned Overend won the World Championship that year?

    Or do you mean he won a race where the level of competition was low enough that his talent could overcome the disadvantage from his equipment?

    Only one test of each tire? Do five tests of each where you let air out and re-pump to pressure so we can see how repeatable your test is. For all I know, the difference you see between tires could...
