Narrative:

Arrived at the aircraft; reviewed the logbook and performed preflight duties routinely. Only thing of note was two new tires on the aircraft. Approximately 30 [minutes] after takeoff I looked at the log book again and noted a discrepancy. The page for our current flight was normal as far as I could tell; to include awr. The previous page detailed the two tire changes. One entry showed the following discrepancy. Discrepancy: medium large transport tire 9; worn beyond limits. Corrective action: right&right tire 10. The tire described as worn was not the one documented as replaced. Not sure what I can say; I just missed this error.

Title: Captain reported confusion regarding a main tire and wheel assembly replacement and the logbook entries that resulted in a flight delay and maintenance action.

Narrative: Arrived at the aircraft; reviewed the logbook and performed preflight duties routinely. Only thing of note was two new tires on the aircraft. Approximately 30 [minutes] after takeoff I looked at the log book again and noted a discrepancy. The page for our current flight was normal as far as I could tell; to include AWR. The previous page detailed the two tire changes. One entry showed the following discrepancy. Discrepancy: MLG Tire 9; worn beyond limits. Corrective Action: R&R Tire 10. The tire described as worn was not the one documented as replaced. Not sure what I can say; I just missed this error.
