he still assumes that a wheel/tire combonation is a rigid body of uniform mass distribution, which it isn't. It's simplified some, but a decent analysis from what I saw briefly scanning it.

Most of the weight of a wheel is at the outer circumfrence, isn't it?

the rim is the "heavy" part of a wheel. But there's still weight spread out in different densities throughout the wheel, and then you have to add in the tire, and it's weight at different radius' throughout the system.

Ya, everything you've said is on the money, my question was unrelated to your previous comments. What I'm curious about is, when comparing a 9 pound wheel to a 16 pound wheel of the same dimensions, where is the weight typically saved? Im thinking most of the savings is towards the center.
