Narrative:

Immediately after landing on runway 12 at iad, the 2 left tires blew and aircraft settled onto the rims. Aircraft swerved to the left and was corrected back to centerline. A lot of aircraft vibration occurred. Passenger were kept seated as no additional problems were noted after aircraft came to a stop. Tower confirmed no additional problems as did the emergency response crew. Passenger were offloaded onto mobile lounges and xported to the terminal. Passenger were calm through incident. Supplemental information from acn 520503: at touchdown, appeared right wing rising. Realized left side was low. Aircraft started drifting left. Captain corrected to centerline. Vibration started shortly after touchdown and increased during rollout. Supplemental information from acn 520507: tower reports seeing excessive smoke on touchdown. Fire trucks responded and reported no fires but tires had come off rims. Callback conversation with reporter acn 520503 revealed the following information: the first officer, who was the PNF, reports no feedback from maintenance as to the cause of the problem. However, both tires, as reported by passenger blew immediately at touchdown. There was suspicion that there may have been antiskid problems. There was no crosswind or side-slip of the aircraft on touchdown.
