Stucked in Sao Tome - Damaged Tyre

A trip to Sao Tome which is suppose to be just a turn around, end up as a night stop. During transit check found that one of the wheel have a multiple damaged beyond maintenance manual limit. There is few cut , thread chunking cut which pass through the cut protector and exposing the carcass ply, plus there is few more circumferential cuts that makes the wheel is good enough to ground the aircraft.


If we compare the damaged with reference to tyre nomenclature diagram below, it seem that the damaged is not that serious, however with the speed involved during take-off plus the effect of pressurization in flight, we have to consult the manufacturer first before decision made to release the aircraft.
