You claimed that braking distance was unaffected.  What experimental
data do you have that led you to that conclusion?

Psssst:  "The ABS worked and the car came to a stop" is not experimental
data that leads one to conclude that "braking distance was unaffected".




...for the tire in question.



Elmo doesn't have to run the experiment.  YOU made the claim and left it
hanging out there; the public wants to know, HOW do you know what you
claimed?

It's a simple question, really, one that you've worked overtime to dance
around.

How do you know what you claimed?

Psssst:  "the car stopped" does not speak at all to "braking distance is
unaffected," which was your actual claim.

Why are you refusing to provide data to back up your claim?

Why are you INSTEAD working very hard to twist this into "it's everyone
else's job to provide the data" for your claim?




Ah.  So you admit, you are a sociopath.

That's progress.

This morning as I was driving into work, I realized there is a way I
might do some stopping distance tests and share the results for free.

I have a number of projects on my 'fun list' and one of them is an
optically based, collision avoidance, automatic cruise control, and
lane following system. The collision avoidance needs to know the
stopping distance under a number of different conditions. So I would
have to measure the stopping distance to make sure the safety zone is
larger than the stopping distance. A fun project, it joins a queue of
projects in my "job jar." So when this particular project reaches the
top of the queue and I start work, I'll be happy to share braking
metrics. It is not needed for 'Prius Tire Tuning' the subject of this
thread.

We already know the ABS is working perfectly with these Sumitomo T4
tires. ABS moderates the braking force to be very close to the optimum
braking force by measuring changes in wheel rotation of the tires.
Furthermore, these tires with a 4/5 Consumer rating for stopping on
dry pavement. Finally, the physics tell us that braking distance is
not a function of tire diameter but only the coefficient of friction.

In engineering, we say, "GOOD, FAST, CHEAP, pick two." Without funding
to change the priority, your request for data will have to wait . . .
"NOT FAST." So once again 'Elmo', you are so my bitch. Still it may
help to let folks understand my current Prius projects:

1) Testing boron CLS as an engine oil additive - I sent the engine oil
samples for testing this morning and should have results early next
week.
2) Purge tank and back to optimum gasoline - during the recent
tornadoes, I had to use an inferior gasoline to keep the Prius Power
running. So I ran it out of gas yesterday evening on the way home.
3) Wife's sine-wave inverter - for her 1.8L, ZVW30 Prius, I've ordered
a 1.5kW, pure sine wave inverter and will be integrating it into her
car when it arrives. This will provide 12A of 120VAC over the 8A of
our NHW11 which uses a modified sine wave. Between the two, we should
have plenty of power for the next outage including enough to power a
couple of neighbors.
4) Backup camera, GPS, blue-tooth, and AVI rear view mirror - my local
mechanic has a kit that I've hired him to install in our NHW11, 2003
Prius. This will improve backup safety and provide a lot of
functionality that the car currently lacks.
5) Transaxle oil testing - since I changed the transaxle oil in
addition to the engine oil testing of boron CLS, I sent a sample for
testing and should have the results early next week. Preliminary
investigation of the pan debris as well as general appearance and
smell, Type WS is an acceptable, even desirable, alternative to the OE
Type T-IV.

These are the projects I'm actively working. I have a longer list of
projects in various states of suspense. So if you want a braking
distance measurement but are unable to pay for it or too lazy to do it
yourself, then you'll just have to wait ... 'Elmo' my bitch.

You at least are consistently dumb.  You keep saying the same thing over
and over, in the hopes that the more you say it the more likely it will
happen or be true.

That's not the case, but you keep trying--and proving the very
definition of insanity.

Remember, Bob, you were the one who brought up not only tire diameter
but also width.  Tell us again what braking distance is a function of.

Go ahead, we'll wait.

Nothing has changed and this is the answer.


Which you dispute without facts and data.


The title of the thread is "Prius Tire Tuning" which means how
different Sumitomo tires affect handling to improve vehicle stability
and modify the hybrid vehicle speed range.


We can only hope. My answer has already been posted, expanded, and now
you've quoted it. Until I start the accident avoidance project, this
is the only answer you're going to get for free. If you want to have
braking distances measured before then, you have options:

(1) hire someone to measure braking distances
(2) make your own measurements
(3) hire me to make measurements
(4) whine about it

You are so my bitch.

wow, you really are that dumb.

Amazing.

I can't wait for the next installment of, "Bob makes a claim and then
demands that everyone else either believe it or prove him wrong".

Or, "Bob makes a claim and then uses jibberish to back it up."
