A latch assembly for use a tire carrier has a wheel plate and a lock bracket and an aperture and a flexible member disposed in the aperture and connected to a wheel plate. The latch assembly has a lock housing, a guide adjacent and a lock arm. The lock arm has one end, another end, a cam surface and a lower cam surface. The one end is pivotally connected to the guide. The lower cam surface extends past the bottom of the lock housing. The weight of the housing acts on a stop member attached to the flexible member, to form a force to urge the lock arms to an unlocked position. When another end is moved toward the lock bracket, the cam surface engages the lock bracket to pivot the lock arm to a locked position so that when the flexible member breaks, the lock arm engages the lock bracket.
