LOL, why would he  give you data of any kind. You don't believe him anyway.

Oh, I get it.  Mr. Charts and Graphs doesn't have to provide actual
data, yet the world is supposed to believe him.

This goes to the heart of the matter. I use data, often plotted, to
make sure I understand how the real world works. I don't mind sharing
this with others but first the real world has to persuade me. In
contrast, you bring no facts and data.. Instead, you substitute
rhetoric and worse.

The natural world is a hard task master and doesn't befriend
fools . . . and neither do I. But I'm not above exploiting the a
fool's folly:

Given both tires have the same pressure, one of the reasons for using
Sumitomo T4s, easily achieved. So the larger diameter tire has less
flex than the smaller diameter. This avoids the flex heating:

This flexing heats the tires by tread, which leads to improved
alignment and lower rolling drag. So I'm reminded of Bob Dylan's

". . .
 wish that for just one time
You could stand inside my shoes
And just for that one moment
I could be you

Yes, I wish that for just one time
You could stand inside my shoes
You'd know what a drag it is
To see you"

Except for when you don't--like with braking performance.  You provide
no data about braking performance on different tires, yet you happily
claim that there is no difference--simply because "you say so".

That puts all of your "data" to question.

In contrast, nature is consistent and doesn't really care about
whining children with a keyboard which is what I like about this chart
showing tire heating effects:

The right hand temperature bands are from a tire with excess camber
and was confirmed with edge wear. To correct it, I bought a camber
adjustment bolt and the tires wear evenly. But the real takeaway is
the tire, relative temperature, the Y-axis. Rolling friction generates
heat and warming the tire is a direct effect. Notice too that higher
pressure leads to less heat.
