Bingo.

I was walking round the park with our daughter earlier and I gave her
the nutshell iTPMS overview and asked her how she thought it might
work ... how the circumference could become shorter for the iTPMS to
'sense' the increased RPM.

"As the tyre gets flatter it spreads more and that makes the
circumference shorter and so the revs higher?"

Not convinced and that summary makes no sense either. Why would
the tyre 'spread more' as it gets flatter and why would the circumference
get shorter even if it did

A 27yr old girl gave the right answer instantly when the combined
brains of Turnip and his goblin Streater still cannot!

Bwhahahahahaha ... !!!
