Better? Now that I have that out of the way. Plastic deformation on a tire is always unsafe and can lead to failure.

This was my argument all along. Your conveluted subject changes and misdirection while pulling apart each sentence without reading the point of the post is what caused the argument. Notice how the original posts say that it WILL lead to failure (certainty) and this one said it CAN lead to failure (possibility). Without the math niether of us can be certain. But if it doesn't lead to failure I'm not sure how it's reasonable to argue it's unsafe.The failure rate of anything is 100% on a long enough timeline. If we don't define when its going to happen then to argue the safety of it is pointless.
Also for clarification, the whole science arguement that started wasn't by me. You felt the need to justify what you were saying by trying to bury me in science that I clearly didn't go to school for. I understand basic concepts of physics and how they apply in the world. I never argued that you weren't scientifically acurate to say that it's weaker, I only argued that nothing definitive about the safety concerns can be determined from the information except the single thing defined (weakness).
I don't feel a need to continue with you picking apart every word I say, but I would like some clarification in acceleration not being a force.

a force is any influence that causes a free body to undergo a change in speed, a change in direction, or a change in shape.

Acceleration changes the tire speed in relation to the ground, the direction of the tire (from a stop), and the shape of the tire through centrifugal force and friction with the pavement. Can you clarify why acceleration would not be a force? I'm sure you would break it down into different factors of acceleration, but as a broader term why would it not be right? It doesn't look as simple as placing it in Newton's second law because there are variables to rotation, but it still seems to apply to the description. I would think that if acceleration isn't a force then braking (the removal of rotation) would not be a force. Can you clarify please with a concise thought instead of breaking down each sentence?
@RETed, Sorry about that. I re-read your posts to be clear on your stance and it purely seems to be from a performance/style standpoint. I don't see anything arguing about it not being safe or not working. Clearly my argument with Vex got applied to more people than it should've. Again, sorry.
@Rotary, I wasn't saying it's an argument from the standpoint of being combative, just that it's something that I'm sure could be debated similarly to the stretch concept because it's out of specifications. Not picking sides or anything, I have no experience with over inflated tires to speak from.
