A pilot questions whether operational control procedures are in place in their company's maintenance department to ensure that proper maintenance standards are upheld. He had noticed during a logbook preflight their ce-560XL aircraft had flown 20 flights before the left and right main landing gear (medium large transport) tires had been replaced for having previously excessive low pressures.

Narrative:
During preflight the crew of a cessna-560XL discovered that both the left and right main tires were replaced as indicated on a previous logbook write-up. The write-up indicated the [main] tires were replaced due to low pressure discovered during a maintenance checklist approximately one week earlier. It appears the tires were serviced during that maintenance checklist; however; the pressure was so low that servicing the tires should not have been allowed. The aircraft then flew on approximately 20 flights before the tires were replaced yesterday. It appears there are not operational control procedures to ensure proper maintenance standards are upheld during the maintenance checklist. [Recommend] adding operational control procedures to ensure proper maintenance standards are upheld during the maintenance checklist.
