Narrative:
The runways and txwys at cedar rapids were slick with a light dusting of snow. When cleared for takeoff, I set the parking brake and began a 10 second engine run up at 80% N1. The airplane started to slide forward (3-5') at about 7 seconds into the run up. I released the parking brake and felt an immediate and normal lurch forward. I added more power, pushed the toga button and commanded 'takeoff power.' the takeoff roll was normal up to vr. As I began rotation, I felt a bump and the airplane sagged a little to the right then lifted off. I called positive climb, gear up. The airplane was flying normally. A short time later, the first officer announced that the anti-skid inoperative lights was on, and then it went off. I suspected one or more blown tires on the right, so I asked the tower to check for tire fragments. They confirmed that there were some tire fragments on the runway. We talked to our maintenance facility and to our dispatch over the radio. We also looked at the gear through the gear viewport. We could see tire damage to the right inboard tire. Our planned destination was den, but since the runways at den were snow covered, we elected to land at ord. We had the F/a's prepare the cabin for evacuate/evacuation and the first officer and I read and discussed the evacuate/evacuation checklist. We burned to minimum fuel and landed on runway 9R at ord under red alert. The airplane rolled straight and stayed in the center of the runway. Evacuate/evacuation was not necessary. A mechanic at the scene told me that the left main gear tires blew during the landing roll. No one was injured. Supplemental information from acn 134305: ramp, taxiway and runway covered with snow and ice. I noticed the anti-skid inoperative light was lit. It went out when the gear handle was moved to the off position. Subsequent investigation revealed that there were tire marks along most of the runway at cedar rapids. This indicates that we took off with the brakes locked. Since I heard the brakes release just prior to takeoff roll and felt the aircraft surge forward, it's difficult for me to figure out how this happened. We are now pending an NTSB and FAA investigation.

Title: ACR MLG BLOWS RIGHT SET OF TIRES ON TKOF AND THEN ON LNDG BLOWS LEFT SET. TKOF WAS ON ICY, SNOW COVERED RWY. LNDG WAS NOT.
Narrative: THE RWYS AND TXWYS AT CEDAR RAPIDS WERE SLICK WITH A LIGHT DUSTING OF SNOW. WHEN CLRED FOR TKOF, I SET THE PARKING BRAKE AND BEGAN A 10 SEC ENG RUN UP AT 80% N1. THE AIRPLANE STARTED TO SLIDE FORWARD (3-5') AT ABOUT 7 SECS INTO THE RUN UP. I RELEASED THE PARKING BRAKE AND FELT AN IMMEDIATE AND NORMAL LURCH FORWARD. I ADDED MORE PWR, PUSHED THE TOGA BUTTON AND COMMANDED 'TKOF PWR.' THE TKOF ROLL WAS NORMAL UP TO VR. AS I BEGAN ROTATION, I FELT A BUMP AND THE AIRPLANE SAGGED A LITTLE TO THE RIGHT THEN LIFTED OFF. I CALLED POSITIVE CLB, GEAR UP. THE AIRPLANE WAS FLYING NORMALLY. A SHORT TIME LATER, THE F/O ANNOUNCED THAT THE ANTI-SKID INOP LIGHTS WAS ON, AND THEN IT WENT OFF. I SUSPECTED ONE OR MORE BLOWN TIRES ON THE RIGHT, SO I ASKED THE TWR TO CHK FOR TIRE FRAGMENTS. THEY CONFIRMED THAT THERE WERE SOME TIRE FRAGMENTS ON THE RWY. WE TALKED TO OUR MAINT FAC AND TO OUR DISPATCH OVER THE RADIO. WE ALSO LOOKED AT THE GEAR THROUGH THE GEAR VIEWPORT. WE COULD SEE TIRE DAMAGE TO THE RIGHT INBOARD TIRE. OUR PLANNED DEST WAS DEN, BUT SINCE THE RWYS AT DEN WERE SNOW COVERED, WE ELECTED TO LAND AT ORD. WE HAD THE F/A'S PREPARE THE CABIN FOR EVAC AND THE F/O AND I READ AND DISCUSSED THE EVAC CHKLIST. WE BURNED TO MINIMUM FUEL AND LANDED ON RWY 9R AT ORD UNDER RED ALERT. THE AIRPLANE ROLLED STRAIGHT AND STAYED IN THE CENTER OF THE RWY. EVAC WAS NOT NECESSARY. A MECH AT THE SCENE TOLD ME THAT THE LEFT MAIN GEAR TIRES BLEW DURING THE LNDG ROLL. NO ONE WAS INJURED. SUPPLEMENTAL INFO FROM ACN 134305: RAMP, TXWY AND RWY COVERED WITH SNOW AND ICE. I NOTICED THE ANTI-SKID INOP LIGHT WAS LIT. IT WENT OUT WHEN THE GEAR HANDLE WAS MOVED TO THE OFF POS. SUBSEQUENT INVESTIGATION REVEALED THAT THERE WERE TIRE MARKS ALONG MOST OF THE RWY AT CEDAR RAPIDS. THIS INDICATES THAT WE TOOK OFF WITH THE BRAKES LOCKED. SINCE I HEARD THE BRAKES RELEASE JUST PRIOR TO TKOF ROLL AND FELT THE ACFT SURGE FORWARD, IT'S DIFFICULT FOR ME TO FIGURE OUT HOW THIS HAPPENED. WE ARE NOW PENDING AN NTSB AND FAA INVESTIGATION.
