## Discrepancy

During takeoff the left wing leading edge overheat light illuminated. Aircraft aborted takeoff at 110 knots resulting in 7 blown tires. Passengers were bussed from aircraft to terminal. Repaired shorted and chaffed wires and replaced switch S896. Replaced 7 wheel/tire and brake assemblies. Operational check good.
