AZR - no Zero Growth tyre, but an inmproved design over that then still being used by AF. But that's not the real reason I'd say BA was safe. The real reasons I think a BA Concorde running over the strip would have (probably - we can't be sure) have survived is because:
They'd have used an into-wind runway
The undercarriage would not be missing a vital component
It would not have been overweight
Most important of all, the tanks would not have been over-full (with no air gap to compress!)
In the event of engine damage, the FE would not have closed down a power-producing engine at that stage of flight
