Narrative:

After a smooth landing; we noticed a vibration and noise coming from the nose gear; starting at about 100-90 KTS. It sounded and felt just like when the aircraft rides on the centerline lights. The intensity of this condition started to increase quickly to the point where we knew something was really wrong with the aircraft. At this point; we transferred control to me; since the first officer was the pilot flying. We came to a full stop on the runway; made the 'remain seated' public announcement to the cabin and asked the tower controller to take a look at our tires and the plane in general while we evaluated the situation inside. The controller told us; as far as he can see; both nosewheel tires are blown. I told him that in order to prevent further damage; I didn't want to move the plane in this condition. We called for maintenance. Operation arranged for buses and an air stair and we deplaned the passengers on the runway. Maintenance changed our tires and we taxied to the gate. No one was hurt and the plane was fine too. As the first officer and I tried to figure out what might have happened to the tires; we came to the following conclusion: as I earlier stated; the landing was a perfectly nice landing. There was absolutely no way that the landing could have caused the tires to blow. There was one unusual thing what possibly could have had happened. As we were descending through 12;000 ft to ZZZ; we heard a loud thump and felt a jolt at the same time. First we thought a galley cart fell over. We called the flight attendants but they were wondering what happened as well; since they felt and heard the same thing. All indications in the cockpit were normal; so we came to the conclusion that most likely something large and heavy must have fallen over in the forward cargo pit. After the landing; we immediately suspected that this inflight occurrence must have had something to do with the blown tires. I think the thump and jolt we felt as 12;000 ft was the right nosewheel tire blowing for whatever reason. Once we landed; the shredded pieces of the right tire wrapped around the inside wall of the left tire as the wheel spun up; wore the wall of the tire out; even punctured a hole in it as it was evident when we went downstairs to see what happened.
