Narrative:
Scheduled air carrier service from pit-avp. We weighed approximately 110 K, 28.5K under gross and the outside air temperature was 92 degrees F. We had an aircraft swap at pit prior to this flight and no MEL's were noted. I did a very complete preflight and noted no irregularities to the aircraft. All parts of the operation were normal up to the rotation. There was an aircraft on a 3 mi final for runway 28R at pit when we were cleared for takeoff. Upon rotation we heard what sounded like a pressurization leak. We both checked our cockpit windows to insure that they were secure. I checked the door lights to make sure the doors were all closed. I completed a normal takeoff and turn to the north as requested by the tower. On ATC I heard the aircraft that landed behind us tell the tower there was rubber on the runway. When I selected climb power the vibration on the #1 engine went from .5 to 4.5. I flew the airplane and the captain contacted our maintenance control in pit and he contacted the flight attendants to get their input. With the evidence of the engine vibration/unusual cabin noise/unusual smell from the packs and the report by the flight behind us, we elected to return to pit. I pulled the #1 engine to idle and made a normal approach and landing on runway 32 at pit. An emergency was declared as a precaution. While taxiing to the gate a fire truck reported that our #2 main wheel tire appeared damaged. Indeed the #2 tire had been destroyed during the takeoff roll and rubber was ingested into the #1 engine doing extreme damage to the fan and fan section of the engine.

Title: MLG HAS ENG VIBRATION AND STRANGE SMELL AT ROTATION.
Narrative: SCHEDULED ACR SVC FROM PIT-AVP. WE WEIGHED APPROX 110 K, 28.5K UNDER GROSS AND THE OUTSIDE AIR TEMP WAS 92 DEGS F. WE HAD AN ACFT SWAP AT PIT PRIOR TO THIS FLT AND NO MEL'S WERE NOTED. I DID A VERY COMPLETE PREFLT AND NOTED NO IRREGULARITIES TO THE ACFT. ALL PARTS OF THE OP WERE NORMAL UP TO THE ROTATION. THERE WAS AN ACFT ON A 3 MI FINAL FOR RWY 28R AT PIT WHEN WE WERE CLRED FOR TKOF. UPON ROTATION WE HEARD WHAT SOUNDED LIKE A PRESSURIZATION LEAK. WE BOTH CHKED OUR COCKPIT WINDOWS TO INSURE THAT THEY WERE SECURE. I CHKED THE DOOR LIGHTS TO MAKE SURE THE DOORS WERE ALL CLOSED. I COMPLETED A NORMAL TKOF AND TURN TO THE N AS REQUESTED BY THE TWR. ON ATC I HEARD THE ACFT THAT LANDED BEHIND US TELL THE TWR THERE WAS RUBBER ON THE RWY. WHEN I SELECTED CLB PWR THE VIBRATION ON THE #1 ENG WENT FROM .5 TO 4.5. I FLEW THE AIRPLANE AND THE CAPT CONTACTED OUR MAINT CTL IN PIT AND HE CONTACTED THE FLT ATTENDANTS TO GET THEIR INPUT. WITH THE EVIDENCE OF THE ENG VIBRATION/UNUSUAL CABIN NOISE/UNUSUAL SMELL FROM THE PACKS AND THE RPT BY THE FLT BEHIND US, WE ELECTED TO RETURN TO PIT. I PULLED THE #1 ENG TO IDLE AND MADE A NORMAL APCH AND LNDG ON RWY 32 AT PIT. AN EMER WAS DECLARED AS A PRECAUTION. WHILE TAXIING TO THE GATE A FIRE TRUCK RPTED THAT OUR #2 MAIN WHEEL TIRE APPEARED DAMAGED. INDEED THE #2 TIRE HAD BEEN DESTROYED DURING THE TKOF ROLL AND RUBBER WAS INGESTED INTO THE #1 ENG DOING EXTREME DAMAGE TO THE FAN AND FAN SECTION OF THE ENG.
