Narrative:

On landing rollout approximately 40-60 KTS, we felt a rumble from the right side of the aircraft. I slowed to a very slow taxi speed. It felt like both mains on the right gear were flat. We cleared the runway, made ATC, company, passenger, dispatch and maintenance aware of our problem. We started the APU, shut down engines and made a visual inspection of the right gear. Both tires were flat. We were near maximum landing weight. Ground services unloaded bags and said some were quite heavy. (Our airline uses standard weights.) tires showed damage that may be consistent with striking an object on runway. As of right now we have no idea what caused our flat tires.
