Abstract: A vehicle includes a pair of frame rails elongated along a longitudinal axis, each of the frame rails having a downward deformation zone, the frame rails bendable at the downward deformation zones from a first position to a second position beneath the first position. The vehicle includes a tire supported between the pair of frame rails at the downward deformation zones. The vehicle includes a spare tire retention member supported between the pair of frame rails forward of the downward deformation zones.

Abstract: A collision management system comprising at least one of a guiding-bracket and a catch configured to inhibit forward movement of an under-hung spare-tire during a collision. The guiding-bracket may connect to and extend downward from a floor, or sprung-mass component, of the vehicle. The spare-tire may contact the guiding-bracket during a collision substantially inhibiting further movement, deflecting it downward away from the vehicle, deflecting it toward a suspension component, and/or deflecting it toward the catch. The catch may be connected to and extend upward from a suspension component. The catch may also inhibit spare-tire forward movement, may puncture the tire of the spare-tire, and may pull the spare-tire downward with the movement of the suspension component to which it is attached during the collision.
