OK. But that's what what has been being argued about at least in this
portion of the thread. People keep talking about the centre of the
wheel being closer to the road, which it is, and taking the centre-road
distance as a radius and computing a new circumference based on that,
which would be considerably more than 1% different from that for an
inflated tire.

Which is what matters when computing the speed of the wheel with a flat
tyre against one with a fully inflated tyre, or the figures for that.
