Yes please.

centre of wheel vertically to ground, 320mm vs 315mm

Interesting, and a lot smaller than I would have thought.

So now you have blown up the proof that it must be the
circumference that is changing, because that change is
less than the 0.4% you saw the ABS wheel rotation rate
change by. You bugger :-(

No, in fact he has proved it can't be the radius change because 5 mm in
320mm is *more* than 0.4%. It's around 1.5%.

Ergo it has to be the circumference change due to elasticity

Denial is fascinating to watch



Watching TNP going from denying that the circumference changes

He actually said originally that it changes by less than 1% and it turns
out that he was correct about that and it is now clear that the distance
between the axle and the road changes by much more than that, 3 times
more in fact, at least with that particular car and those tyre pressures.

and
quoting his engineering background as proof and now saying it does change
is fascinating. It makes you wonder how he expects anyone not to notice.
