A canadair CL65 on takeoff roll veered to the right due to misaligned nosewheel steering. The crew used heavy left braking for directional control resulting in the left main tires flat spotted.

Narrative:
On takeoff roll from dca with brake release, aircraft began to turn right. I reduced power and applied brakes hard and stopped the aircraft on the runway. I reset the nosewheel steering and taxied off the runway. I checked the steering and brakes -- both were normal. Then I elected to depart. The takeoff and flight and landing were all normal. When we landed at rdu during the postflt aircraft check, we discovered both tires on the left main gear were flat-spotted and had to be replaced. It appeared that the nosewheel steering tiller did not center completely so the takeoff roll started to the right, heavy braking caused the tire to slide.

Title: A CANADAIR CL65 ON TKOF ROLL VEERED TO THE R DUE TO MISALIGNED NOSEWHEEL STEERING. THE CREW USED HVY L BRAKING FOR DIRECTIONAL CTL RESULTING IN THE L MAIN TIRES FLAT SPOTTED.
Narrative: ON TKOF ROLL FROM DCA WITH BRAKE RELEASE, ACFT BEGAN TO TURN R. I REDUCED PWR AND APPLIED BRAKES HARD AND STOPPED THE ACFT ON THE RWY. I RESET THE NOSEWHEEL STEERING AND TAXIED OFF THE RWY. I CHKED THE STEERING AND BRAKES -- BOTH WERE NORMAL. THEN I ELECTED TO DEPART. THE TKOF AND FLT AND LNDG WERE ALL NORMAL. WHEN WE LANDED AT RDU DURING THE POSTFLT ACFT CHK, WE DISCOVERED BOTH TIRES ON THE L MAIN GEAR WERE FLAT-SPOTTED AND HAD TO BE REPLACED. IT APPEARED THAT THE NOSEWHEEL STEERING TILLER DID NOT CTR COMPLETELY SO THE TKOF ROLL STARTED TO THE R, HVY BRAKING CAUSED THE TIRE TO SLIDE.
