Axle mounted tire shrapnel containment shield
Apparatus and associated methods relate to a tire containment device securely mounted to an axle of a vehicle to contain shrapnel caused by a tire blowout. In an illustrative example, the tire containment device may include an axle bracket and a tire fender. The axle bracket, for example, may be mounted to an axle of the vehicle. The tire fender may, for example, have a substantially continuous containment cavity. In some examples, when the tire fender is coupled to a vehicle axle by the axle bracket, the containment cavity may extend over at least a top and an exterior face of an upper third of a diameter of a tire. For example, the containment cavity may substantially intercept shrapnel from failure of the tire before it reaches a body of the vehicle. Various embodiments may advantageously reduce damage to a body of the vehicle during a tire blowout.

6. The tire shrapnel protection device of claim 1 , wherein the front panel, the back panel, and the tread cover are cut from a single four-foot by eight-foot sheet of material.
7. The tire shrapnel protection device of claim 1 , wherein the front panel, the back panel, and the tread cover comprises plate steel at least one-sixteenth inch thick.
8. A tire shrapnel protection device comprising:
an axle bracket; and,
a tire fender having a substantially continuous containment cavity configured such that, when the tire fender is coupled to a vehicle axle by the axle bracket, the containment cavity extends over at least a top and an exterior face of an upper third of a diameter of a tire such that the containment cavity intercepts shrapnel from failure of the tire before it reaches a body vehicle;
wherein the tire fender comprising:
a tread cover having a width greater than a width of the tire and extending from a first edge to a second edge along a curvilinear path defined by an inner bounding diameter greater than the diameter of the tire;
a front panel releasably coupled to one or more tabs of the tread cover at a front perimeter thereof; and,
a back panel coupled to the tread cover at a back perimeter,
wherein the front panel and the back panel are each coupled to a corresponding face of the tread cover at the first edge and at the second edge such that, when the shrapnel impacts at least one of the first edge and the second edge, at least one of the front panel and the back panel apply a tensile force between the first edge and the second edge along a mechanical path having an effective diameter less than the tire diameter.
9. The tire shrapnel protection device of claim 8 , wherein the tread cover has a width greater than a total width of two tires.
10. The tire shrapnel protection device of claim 8 , wherein the substantially continuous containment cavity comprises apertures of less than 1 inch in diameter.
