Taxied from the FBO to the runway at ZZZ. After being cleared for takeoff started the takeoff roll and began to feel the nose-wheel start to shake around 40 knots. The takeoff was aborted and we exited the runway. The nose-gear pin was most likely not secured completely allowing it to wiggle loose during taxi. There was minor damage to the nose-wheel(tire only) but it remained completely inflated. We re-secured the gear pin and taxied to FBO whereas our company maintenance arranged for the tire to be changed. Work was performed and signed off by maintenance.
On takeoff roll nose wheel started vibrating and we realized the nose wheel pin was not installed. We didn't get far down runway about 40 knots; So we aborted takeoff. Put the pin in on taxiway taxied back to FBO; and saw that there was some damage to tire. Told our management and they decided to change the tire.
Air Taxi flight crew reported during takeoff the nose wheel was vibrating due to the nose gear pin not secured so they rejected the take off and taxied back to the FBO.
