Narrative:

During the first officer's preflight at the outstation, the right side nose tire was found to be worn down to the cord in one area. Maintenance control was contacted and the item recorded in the maintenance log. Contract maintenance was called to inspect the tire and, to most everyone's surprise, signed-off the tire as within limits for 1 revenue flight to a maintenance base. So, we flew passenger 1 leg back to our hub where maintenance was standing by to change the tire. That mechanic asked if we had ferried the plane in. I said 'no' because the contract mechanic had approved our 1 revenue flight. I showed our mechanic the write-up and sign-off. His response was 'bull....' the union representative I talked to about this flight was also quite skeptical about the validity of the contract mechanic's sign-off and suggested I write this report.
