I remember when PPRuNe was actually discussions among professional pilots.
No wonder I hardly ever log on anymore.
You do not do the site justice, it is very informative.
This particular discussion has made explicit that there is no mandatory tire monitoring even on fairly modern wide bodies, that a crew has no simple way to find out if their running gear is healthy and that a 767 will roll on its rims quite readily.
One can perhaps assume the tires were intact for much of the runout, as the anti skid system would probably have had difficulties otherwise. Still, it would help to know where along the runway the tire debris were found.
