As at this point in the proceedings we don't know if it was one or both tyres that caused the loud "bang" and it is not SOP to stop for a blown tyre we have to assume that the reason for stopping was that directional control of the aircraft was in doubt....... And it IS SOP to stop for control problems.
Anyhow well done to the crew, no one hurt and no more damage to the aircraft just a lot of noise from the PPrune gallery Microsoft pilots.
