Tapping the brakes might normally be trying to stop 300-400T of rolling force.

A 747 tyre spins at approx 1,250 RPM during rotation at 160kts, tapping the brakes with zero load, I'd imagine, would stop the wheel instantly so yes I'd imagine the tyre would spin down on the rim, obliterating the bead seat and flattening the tyre, fortunately the valve stem is part of the wheel rim and not the tyre so it would be fine
