Please quote my previous response as it makes things easier to keep track of.

The point about not being at max load wasn't as much a reference of the fact that it determines the whole criteria, but that it plays a role in the original engineering specifications. When I say that it's not at its maximum rating on an average vehicle I'm just saying that if it isn't at it's maximum load then changing the load (large assumption here) might have some wiggle room. <-I know there's no way you'll concede to that point.

Honestly there's too much variability to say for certain. For a regular all terrain tire it very well may have enough 'room' to work in a stretched application as their made with different constraints in mind where as high performance tires with high speed ratings may not (lean manufacturing; basically means that the FoS gets closer to 1).

I had to read the gun reference a couple times to pick up the point you were making there, still not 100% sure I understand what you're saying about the non-firing round. (I'm not a gun person, I stay away from them.)

That's fine. It's the same as the master cylinder analogy.

I did understand the brake master reference. That's an excellent reference for anyone that has driven with a leaking brake master. I could definitely see how the two correlate. That's your best argument yet for real world relation IMO. (this was the thing I was trying to do previously with coffee and baseball bat references, it's hit and miss sometimes with metaphors)

Your reply of "Not really" is the point I've been trying to make the whole time. If you didn't see ANY validity in what I said you would've answered "No", but you did see some truth in what I'm saying. You don't agree with it as being safe by engineering standards, but obviously have to accept that the possibility that it will hold is true. I am willing to more directly concede. My only point this whole time was to get acknowledgement that it's possible it's safe (from a standard of holding for the life of the tire). I'm not saying it is, I agreed with your statements of material sciences from the get-go and agree that there will be deformation on the tire. All I've argued is that it's possible that it will hold and get you safely from point A to point B for the life of the tread. I understand your stance of safety and agree that there is definitely a possibility that it could fail as well based on using it outside of its designed specifications.

Not to be a dick, but that's a contradiction. Safety does not include taking a chance where it can be eliminated. Sure you could get to point A to point B, but will you make it every time with a stretched tire? It's the same issue with the leaking MC. How often can you make that trip with the cylinder like that? Once? Twice? Forty? It's a gambit at best.

For the vulcanized rubber, where am I looking this up and what types of numbers am I looking for?

Check the Matweb website, I found this one, but if you want to use a different rubber feel free to find it:

We want the mechanical properties.
