Thanks for quoting.

Yes. As the tire is already stressed outside of spec; damage to the wheel is more than likely to result (not to be confused with the tire). Normal blow out allows for material sacrifice to save the wheel. This is of course dependent upon the amount of stretch on the tire. The closer the stretch is to stock spec the more material will be available to sacrifice in maintaining the wheel.

I also found this one (and a couple others of different particle mesh size) but no mechanical properties are listed.

I didn't see a way to post it here that would be easy to read so I separated the fields using astrix..
Would you mind explaining what the "elongation at break" field means? It seems at a glance that it would mean that it can stretch 1-8x its length before breaking... that seems like a HUGE range.

Elongation at break is the elongation of the material at catastrophic failure during a tensile test. During material testing they install a test piece similar in design to these:
Elongation is the final distance (if given in percentage the final distance divided by the original) the sample is able to make it. This is not the same as failure (encroachment into plastic region of deformation).
