C-172 pilot reported a loss of directional control during landing rollout due to a flat tire on landing. The aircraft stopped safely on the runway and was provided a tow to the FBO.

Narrative

While rolling out after briefed normal landing on Runway XX at ZZZ; I felt a shudder from the left main landing gear and heard a beating sound from the same general area. The aircraft experienced a very sudden onset of a left turning condition near simultaneously; pulling me off centerline and towards the left edge of the runway. I noticed the exit for the taxiway was close by so I added power and right rudder to attempt exiting Runway XX at taxiway. As soon as those inputs were applied; I determined they were not helping the situation; so I pulled power and came to a stop on Runway XX. The aircraft remained fully within the confines of Runway XX and did not strike any objects prior to coming to a stop. The Tower Controller asked if there was a reason I was now stopped on Runway XX. I informed them the aircraft appeared to have a flat tire on the left main landing gear and I was unable to safely move the aircraft from Runway XX. Tower asked if they could coordinate ground services on my behalf and I responded yes. At this point; I shut the aircraft down and using a handheld transmitter; I coordinated with Tower for my passenger to depart the aircraft and walk to the terminal via taxiway; crossing taxiway and into the parking area. Tower approved the request and informed me the FBO would be able to tow me off the runway shortly. While waiting for recovery; I inspected the left main tire and noticed the inner tube valve was missing from the wheel and had been sucked into the tire where it remained attached to the tube. Within an hour the FBO was able to put the left main landing gear on a dolly and tow the aircraft to parking where it was secured and follow-on repairs were coordinated. This occurred on the return leg of a cross country flight from ZZZ. Prior to departing ZZZ; I completed a normal pre-flight using the flow in the POH and verifying with the checklist. The left main tire had a known flat spot however no cords were visible during the pre-flight inspection. There was no history of air being added to the tire in several flights and it appeared no air needed to be added to either main tire or the nose tire during pre-flight. During the take-off roll at ZZZ; there were no indications any tire was not at the appropriate pressure. Human performance considerations: Visual inspection of tire pressure may not result in discovery of an underinflated tire; a tire pressure gauge is a simple and inexpensive device that can quickly be used during the pre-flight to determine if air pressure needs servicing prior to take-off.
