You seem to be missing the point.

"Could prove detrimental". Based on your lack of evidence you can't say that its a certainty, thus your information is not any more correct than mine.Theory is not proven, that's why there's a special word for it.

Show me where I said could.

As for the tire inflation, I keep the tires at a reasonably high pressure setting of 40psi to maintain that the lack of flex in the elastic region.

You do not mean what you think you mean. Let me give you a little example:

Plastic deformation is never good in such a thing.

The thing is that you're arguing that I don't want my tires to act the way I actually want them to act.

...What?

This is a preference, telling someone how they should prefer something is... useless. Technically I'm sure I'm putting more pressure on the sidewall than the manufacturer recommends, but I don't think it's more than the tire can take.

From whence cometh this surety?

If the tire can hold up to constant flexing from racing a car and being throw into corner after corner, it doesn't seem (to me) like it wouldn't be able to take that pressure as a constant.

Again, apples and oranges. Momentary load in the elastic region will not cause plastic deformation of the tire.

Otherwise it would be very common for people to have the sidewall blow out of their tires while racing. Obviously this is my personal opinion on the matter, just like you have yours.

Mine's not opinion. I'm stating material mechanics.

Without hard technically data that I can't prove my point and you can't prove yours. Your information is speculation and theory.

Actually, mines based on material mechanics which is a proven science. Additionally you can test them yourself. I'll explain how following this.

My information is real world testing on my car (that I'm sure can be effected by a million different factors that I can't measure), my experience says it works though without detrimental effects.

Your experience is limited, and based on false presumptions.

Take a brand new tire prior to mounting. Measure all dimensions and record them. Stretch your tire and mount it. Run it a few times on the track, then remove the wheel and measure again. Are the measurements going to be the same? Depending on the amount of stretch will dictate whether you're in the plastic or elastic region of the material. Do the same with a non-stretched tire, dimensions will be almost if not identical.

If you're stretching the tire outside of manufactures spec and then putting lateral load on the tire I guarantee you will be engaging in the plastic region.
