An axle jack includes a support column extending along a longitudinal axis between a top end and a base end. An axle plate is coupled to the top end of the support column and a base plate including an upper surface and a lower surface is coupled to the support column base end. One or more gussets are arranged between the base plate upper surface and the support column and a handle projects from the support column at a position intermediate the top and base ends of the support column. Gripping protrusions are formed on the lower surface of the base plate.

1. An axle jack, comprising: a base plate having an upper surface, a lower surface, a forward edge and a rearward edge;a support column mounted to the base plate upper surface near the base plate rearward edge, distal from the base plate forward edge;an axle plate mounted to the support column distal from the base plate;a plurality of treads configured for removable assembly to the base plate lower surface, each of the treads having a width, a length, and a depth configured to securingly conform to a width, a length and a depth of the base plate, each of the treads comprising: an exterior surface;an interior surface;a rear walla front edge of the exterior surface, the front edge spaced apart from the rear wall;a right wall;a left wall spaced apart from the right wall, each of the right wall and the left wall continuously disposed between the front edge and the rear wall, each of the right wall and the left wall having a continuous external edge and a lip continuously disposed along the external edge in a position parallel to the interior surface, wherein each of the left wall and the right wall has a height substantially equal to a height of the base plate;a gap between the lip of the right wall and the lip of the left wall, wherein the gap and the lip of each of the right wall and the left wall have a total combined width substantially equal to the width of the base plate; anda receiving channel defined by the right wall, the left wall, the lip of each of the right wall and the left wall, and the interior surface;wherein the receiving channel has a width, a length, and a depth substantially equal to the width, the length, and the depth of the base plate;wherein the receiving channel slidingly engages the base plate;wherein upon the sliding engagement of the receiving channel to the base plate, the interior surface of the tread is directly adjacent the lower surface of the base plate;wherein the plurality of treads comprising a first tread, a second tread, and a third tread;wherein the exterior surface of the first tread comprises a center portion centrally disposed between the rear wall, the front edge, the right wall, and the left wall, the center portion comprising a plurality of obround humps arranged in a pair of rows, the humps of one of the rows being off-set from the humps in the other row;wherein the exterior surface of the second tread comprises a plurality of V-shaped protuberances, wherein substantially all of the protuberances have an apex, wherein the apices are centrally aligned from the front edge to the rear wall, wherein the protuberances are disposed on the entire exterior surface of the second tread; andwherein the exterior surface of the third tread comprising a plurality of triangular bumps disposed on the entire exterior surface, wherein the bumps are arranged in alternating configuration of a pair of the bumps alternating with a single one of the bumps from the front edge to the rear wall. 2. The axle jack as set forth in claim 1 wherein the jack is more resistant to tipping in a first direction than in a second direction opposite the first direction. 3. The axle jack as set forth in claim 1 further comprising a handle mounted to the support column and extending toward the base plate forward edge. 4. The axle jack as set forth in claim 1 wherein the axle plate further comprises an axle support surface. 5. The axle jack as set forth in claim 4 wherein the axle support surface comprises a concave shape configured to cup a vehicle axle. 6. An axle jack, comprising: a support column having a top end and a base end, the support column extending along a longtidinal axis;an axle plate coupled to the top end of the support column;a base plate coupled to the base end of the support column, the base plate including an upper surface and a lower surface;at least one gusset arranged between the base plate upper surface and the support column;a handle projecting from the support column at a position intermediate the top and base ends of the support column;a reflective tape coupled with the support column at one or more positions intermediate the top and base ends of the support column;a plurality of gripping protrusions formed on the lower surface of the base plate;a plurality of treads configured for removable assembly to the base plate lower surface, each of the treads having a width, a length, and a depth configured to securingly conform to a width, a length and a depth of the base plate, each of the treads comprising: an exterior surface;an interior surface;a rear walla front edge of the exterior surface, the front edge spaced apart from the rear wall;a right wall;a left wall spaced apart from the right wall, each of the right wall and the left wall continuously disposed between the front edge and the rear wall, each of the right wall and the left wall having a continuous external edge and a lip continuously disposed along the external edge in a position parallel to the interior surface, wherein each of the left wall and the right wall has a height substantially equal to a collective height of the base plate and a height of a tallest one of the gripping protrusions;a gap between the lip of the right wall and the lip of the left wall, wherein the gap and the lip of each of the right wall and the left wall have a total combined width substantially equal to the width of the base plate; anda receiving channel defined by the right wall, the left wall, the lip of each of the right wall and the left wall, and the interior surface;wherein the receiving channel has a width, a length, and a depth substantially equal to the width, the length, and a combined depth of the depth of the base plate and a depth of the tallest one of the gripping protrusions on the lower surface;wherein the receiving channel slidingly engages the base plate;wherein upon the sliding engagement of the receiving channel to the base plate, the interior surface of the tread is parallel to and proximal the lower surface of the base plate;wherein the plurality of treads comprising a first tread, a second tread, and a third tread;wherein the exterior surface of the first tread comprises a center portion centrally disposed between the rear wall, the front edge, the right wall, and the left wall, the center portion comprising a plurality of obround humps arranged in a pair of rows, the humps of one of the rows being off-set from the humps in the other row;wherein the exterior surface of the second tread comprises a plurality of V-shaped protuberances, wherein substantially all of the protuberances have an apex, wherein the apices are centrally aligned from the front edge to the rear wall, wherein the protuberances are disposed on the entire exterior surface of the second tread; andwherein the exterior surface of the third tread comprising a plurality of triangular bumps disposed on the entire exterior surface, wherein the bumps are arranged in alternating configuration of a pair of the bumps alternating with a single one of the bumps from the front edge to the rear wall. 7.
