Would a blow out with a stretched tire be worse or harder to control in some way?

Yes it would be more dangerous as you would be trying to drive on metal instead of rubber. The dynamic coefficient of friction is small when compared to rubber, thus control is going to be more difficult. If the blow out happens on the front you will have very little or no response from that tire. The rears will be similar. This is of course holding that the failure is on the material side of things.

The explaination was what I was looking for (the picture helped). I wasn't relating this to tires though, I was just wondering why the technical information about the material had such a wide range of data. Seems either really unpredictable or there is a lot of data that we aren't getting. I would imagine to have an 800% discrepancy there would have to be a lot of tests with different compounds, temperatures, etc.

Tests are standardized. Temperature is a variable that can be tested for as for different mixtures of vulcanized rubber (that's where the proprietary rights begins coming in).
