Most likely a severely under-inflated tire that had heated up to the temperature at which a tire will self destruct and catch fire. Unfortunately once a tire reaches that point it is impossible to overcome the chemical reaction and put out the fire.
The coach was doomed!
Thank God that no one perished because of this situation.
For those people not using a reliable TPMS, take notice.
