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 ******ing force due to rolling resistance. How can you justify including the first, but ignore the second? Perhaps you meant changes in the coefficient of rolling resistance which will depend on tire size, construction, and inflation pressure; but not on weight.
