Acknowledged and understood. My point (which does not contradict yours) is equally simple - that the crew had no way of knowing that at the time, and as such would have assumed a worst-case scenario to cover all possibilities.
@Lyman (below) - that's an assumption. The evidence we have of tyre failures causing subsequent damage to Concorde suggest that in the cases where root cause was investigated, there were mechanical factors leading to failure of the tyre. The other incidents were never investigated to that level - there has never been a documented case of a Concorde tyre incident where there was no plausible explanation for the tyre failure (and thus no evidence to suggest tyres failed "spontaneously").
