It can change *shape* but not *length* (except by 1% or so, which no
one is disputing), and that is what I say above.

Now that we know that we're talking about detecting speed changes
under 0.5% you can't discount a circumference change of 1%

A flat will change by more than 0.5% as shown empirically by another
poster.

Its also fairly obvious that it will from the destruction of one twin
wheel tyre on a lorry. If it only changed by say 1% the tyre wouldn't
generate enough heat to destroy it and its the heat that does it.

It isnt heat that sees the entire tread come off on a twin wheel tyre,
that is due to the retread coming off.

Then some clown reports that they have seen a crocodile on the motorway.
