Narrative:

The approach was normal and the speed was as appropriate, 120 KIAS. The transition to landing went smoothly. I made all appropriate calls while the captain slowed the plane and landed. There was a slight crosswind from the right of about 5-7 KTS. The captain set the right main down very softly, almost as if it didn't touch, then the left main. The nose came down and all appeared normal. He touched down in the first 1000 ft of runway as the nose came down. The tower advised us that we had smoke from our right mains and they said it appeared we blew a tire as the aircraft decelerated. We noticed it leaning to the right and it felt rougher like the tire was flat. The captain maintained the centerline until the taxiway turnoff about 1/2 way down the runway. He took care in slowing so as not to lose directional control. We turned off at the taxiway and advised tower that we had to shut down there to prevent any damage to the wheels. We asked for crash/fire/rescue to come out to be sure there wasn't any problems or chance of fire. We advised the company ground station to send a bus for the passenger. We kept the passenger on board since there was no danger and waited for the bus. Meanwhile, we went outside, assessed the damage, notified our company. Both our right main tires failed and broke apart. The brakes were also warped as if extremely heated. No braking had taken place, however, when the smoke and blown tire was noticed by tower. Also, the parking brake was not set and the anti skid system was armed. This was our first flight of the day. Cause of the tire failure or brakes as far as I know hasn't been determined.

Title: BOTH R MAIN GEAR TIRES FAIL DURING A NORMAL SMOOTH LNDG.

Narrative: THE APCH WAS NORMAL AND THE SPD WAS AS APPROPRIATE, 120 KIAS. THE TRANSITION TO LNDG WENT SMOOTHLY. I MADE ALL APPROPRIATE CALLS WHILE THE CAPT SLOWED THE PLANE AND LANDED. THERE WAS A SLIGHT XWIND FROM THE R OF ABOUT 5-7 KTS. THE CAPT SET THE R MAIN DOWN VERY SOFTLY, ALMOST AS IF IT DIDN'T TOUCH, THEN THE L MAIN. THE NOSE CAME DOWN AND ALL APPEARED NORMAL. HE TOUCHED DOWN IN THE FIRST 1000 FT OF RWY AS THE NOSE CAME DOWN. THE TWR ADVISED US THAT WE HAD SMOKE FROM OUR R MAINS AND THEY SAID IT APPEARED WE BLEW A TIRE AS THE ACFT DECELERATED. WE NOTICED IT LEANING TO THE R AND IT FELT ROUGHER LIKE THE TIRE WAS FLAT. THE CAPT MAINTAINED THE CTRLINE UNTIL THE TXWY TURNOFF ABOUT 1/2 WAY DOWN THE RWY. HE TOOK CARE IN SLOWING SO AS NOT TO LOSE DIRECTIONAL CTL. WE TURNED OFF AT THE TXWY AND ADVISED TWR THAT WE HAD TO SHUT DOWN THERE TO PREVENT ANY DAMAGE TO THE WHEELS. WE ASKED FOR CRASH/FIRE/RESCUE TO COME OUT TO BE SURE THERE WASN'T ANY PROBS OR CHANCE OF FIRE. WE ADVISED THE COMPANY GND STATION TO SEND A BUS FOR THE PAX. WE KEPT THE PAX ON BOARD SINCE THERE WAS NO DANGER AND WAITED FOR THE BUS. MEANWHILE, WE WENT OUTSIDE, ASSESSED THE DAMAGE, NOTIFIED OUR COMPANY. BOTH OUR R MAIN TIRES FAILED AND BROKE APART. THE BRAKES WERE ALSO WARPED AS IF EXTREMELY HEATED. NO BRAKING HAD TAKEN PLACE, HOWEVER, WHEN THE SMOKE AND BLOWN TIRE WAS NOTICED BY TWR. ALSO, THE PARKING BRAKE WAS NOT SET AND THE ANTI SKID SYS WAS ARMED. THIS WAS OUR FIRST FLT OF THE DAY. CAUSE OF THE TIRE FAILURE OR BRAKES AS FAR AS I KNOW HASN'T BEEN DETERMINED.
