You tire is only 1" to 2" wide, your car tire are typically 35 PSI, trucks around 50 PSI, so that is the pressure I assumed. Mind you, 1100K is pyrolization temperature, I would guess that at 800/900 K the tire would lose integrity due to creep (plastic deformation) and ends up completely distorted. That tire did not look distorted, a little scorched and blown up.
