Narrative:
First officer was doing the takeoff. At 80 KIAS, I noticed #1 EPR at 1.45, #2 EPR read 1.30-1.32. Other engine indications were normal. I looked at the speed and saw 90-100 KTS. I announced abort and retarded the throttles. Tower was notified and the passenger were told to remain seated. After taxiing off the runway, the first officer contacted maintenance control and informed him of the abort, of hot brakes and the brake temperatures. Maintenance control requested that we return to the gate. Den maintenance was then called and informed of the reason for the abort and that we had hot brakes. We requested chocks and for personnel to remain clear of wheels. They acknowledged and complied. After the final turn into parking, the marshal signaled to stop. He came on interphone and announced that one tire had just gone flat and that we would be towed the rest of the way. After the tow in, the remaining tires went flat. Engine shutdown procedures were normal.

Title: AN A320 ACFT'S TIRES GO FLAT AFTER A LOW SPD ABORT AT 100 KTS BECAUSE OF A MISMATCH OF THE EPR READING ON TKOF FROM DEN, CO.
Narrative: FO WAS DOING THE TKOF. AT 80 KIAS, I NOTICED #1 EPR AT 1.45, #2 EPR READ 1.30-1.32. OTHER ENG INDICATIONS WERE NORMAL. I LOOKED AT THE SPD AND SAW 90-100 KTS. I ANNOUNCED ABORT AND RETARDED THE THROTTLES. TWR WAS NOTIFIED AND THE PAX WERE TOLD TO REMAIN SEATED. AFTER TAXIING OFF THE RWY, THE FO CONTACTED MAINT CTL AND INFORMED HIM OF THE ABORT, OF HOT BRAKES AND THE BRAKE TEMPS. MAINT CTL REQUESTED THAT WE RETURN TO THE GATE. DEN MAINT WAS THEN CALLED AND INFORMED OF THE REASON FOR THE ABORT AND THAT WE HAD HOT BRAKES. WE REQUESTED CHOCKS AND FOR PERSONNEL TO REMAIN CLR OF WHEELS. THEY ACKNOWLEDGED AND COMPLIED. AFTER THE FINAL TURN INTO PARKING, THE MARSHAL SIGNALED TO STOP. HE CAME ON INTERPHONE AND ANNOUNCED THAT ONE TIRE HAD JUST GONE FLAT AND THAT WE WOULD BE TOWED THE REST OF THE WAY.
