Rubbish.
The tread on the tyre and the side walls deform as the tyre rotates changing the actual circumference. The change depends on the contact length which changes with pressure, load, tread pattern, rubber compound, type of belts, etc.
Even a steel tyre like those on trains deforms as it rotates.
I see T r o l l continues to be unable to actually argue the point.
Well it can't, can it. Except in my very low speed example where the side-wall, being elastic, spirals up (as would be shown up by the painted lines). Of course, a side wall is not designed nor intended to take that type of stress, and would quite soon shear as TNP describes.
I'm still waiting for your answer to this Q.
This "philosopher" hasn't ever noticed the tyre debris on the roads where the tread has been ripped off.
Maybe he wants to explain why it happens to lorries with twin wheels where only one tyre has gone flat but is being kept at about the correct radius by the other wheel?
The factor will be 1.00 or perhaps up to 1.01.
Ah, nice attempt at a shimmy there, Den. Our Dave would be proud of you.
What you're in fact admitting is that the wheel and the tire *must* rotate at the same rate, otherwise the tread would come off.
No. In the context iof this thread it is utterly irrelvant.#
But we don't disagree that the rate changes. Only by how much, and why.
No dennis is a man of limited intelligence who runs on received wisdom because he cant think for himself. Such education he has had has been learning by rote only, and he therefore thinks that being right is a matter of listening to the right authjority. He will probably listen to the BBC, read the Guardian and believes that it is a disater to leave the EU and that mab made global warming is real, not because he has examined the evidence, but because that is what he has been told, endlessly.
You may be right but I was referring to T r o l l, not Troll.
The TNP areshole is wrong as usual, and resorting to stupid attacks over something I haven't said because is is wrong and is trying to divert everyone away from the fact he is wrong like he always does.
Here TNP goes.. all through the thread he has claimed there is no effect and now he claims there is an effect and has done so all along.
How dumb can you be to think that is what I said? I said the exact opposite of what you chose to claim I said.
Are you TNP ?
And when you measure how much the rate changes, that will tell you if it is changing due to the change in circumference or the change in the distance between the axle and the road because one changes much more than the other with under pressure.
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?"
A 27yr old girl gave the right answer instantly when the combined brains of Turnip and his goblin Streater still cannot!
Bwhahahahahaha ... !!!

TNP says (above) that having a wheel rotating at a different rate to the tire is only possible if the tread rips off.
You point out how much tire debris there is around.
QED.
Yup, but he can't help it. He is a left brainer and so will both back himself into a corner and argue black is white until the penny eventually drops and then as you say (and I said a while back) will gradually skew his BS to make it look like he had the answer from the beginning (bit still asked the question)?
It would be sad if he wasn't already a laughing stock. ;-)
Cheers, T i m
No, he is Turnips goblin and they obviously stick together in the false sense that there is safety in numbers.
All that actually means ITRW is they will all fall into the moat at the same time. ;-)
And the same freaks think they have all the answers to Brexit!

As there was nothing on telly tonight, I used my OBD cable to log the four wheel speed sensors over a straight section of road with cruise control set to 50mph, which was measured by VCDS as 77.6kph then let some pressure out of the right rear, turned around, rinse and repeat until the TPMS triggered.
Starting at 39psi the right rear was on average 0.1kph slower than the other three wheels, it triggered after letting it down to 31psi by which time it was on average 0.2kph faster than the other three wheels.
So it triggered on a increased wheel speed of 0.3/77.6 = 0.4%
The numbers don't help with that.
And most of the people (worth considering) agree.
Yup.
Yup.
Ere, tell Turnip and his goblin assistant (Streater) that a part of a train goes backward as the train goes forward and watch their tiny brains explode!
