A compactor wheel tip for a landfill or soil compactor comprises a bottom wall having a wheel engaging surface, a top wall having a ground engaging surface, oppositely disposed front and rear walls having concave surfaces, and oppositely disposed side walls. The ground engaging surface of the top wall may be generally planar and have a “bow-tie”-shaped cross-section, or the top wall may define a pair of shoulders each extending inwardly from one of the side walls, and a rib extending between the shoulders and having a depth that is less than the depth of shoulders. The ground engaging surface may further define a pair of exterior pockets disposed on opposite sides of the rib and extending downwardly between the rib and corresponding portions of the front and rear walls.

1. A compactor wheel tip, comprising: a bottom wall having a wheel engaging surface;a top wall having a ground engaging surface;oppositely disposed front and rear walls extending upwardly from the bottom wall to the top wall, the front and rear walls having a concave shape, with the distance between the front and rear walls being greater proximate the bottom wall than proximate the top wall; anda pair of oppositely disposed side walls extending upwardly from the bottom wall to the top wall,wherein the ground engaging surface defines a pair of shoulders each extending inwardly from a corresponding one of the side walls, and a rib extending between the shoulders and having a depth that is less than the depth of shoulders, andwherein the ground engaging surface defines a pair of exterior pockets disposed on opposite sides of the rib and extending between the shoulders, wherein the exterior pockets extend downwardly between the rib and corresponding portions of the front and rear walls. 2. A compactor wheel tip according to claim 1, wherein intersecting portions of the top wall and the front and rear walls proximate the exterior pockets define upper edges of the respective exterior pockets, and wherein a portion of the ground engaging surface defining the rib is higher with respect to the bottom wall than the upper edges of the exterior pockets. 3. A compactor wheel tip according to claim 1, wherein portions of the front and rear walls proximate the top wall extend outwardly from a first vertical plane bisecting the compactor wheel tip from front to back at a pocket angle Φ with respect to a line perpendicular to the first vertical plane such that the distance between the front and rear walls increases as the front and rear walls extend outwardly from the first vertical plane toward the side walls, and wherein portions of the ground engaging surface defining front and rear walls of the exterior pockets extend outwardly from the first vertical plane at the pocket angle Φ. 4. A compactor wheel tip, comprising: a bottom wall having a wheel engaging surface;a top wall having a ground engaging surface;oppositely disposed front and rear walls extending upwardly from the bottom wall to the top wall with the distance between the front and rear walls decreasing as the front and rear walls extend from the bottom wall toward the top wall; anda pair of oppositely disposed side walls extending from the bottom wall to the top wall and having lateral edges intersecting with corresponding lateral edges of the front and rear walls,wherein the ground engaging surface defines a pair of shoulders each extending inwardly from a corresponding one of the side walls, a rib extending between the shoulders, and a pair of exterior pockets disposed on opposite sides of the rib and extending between the shoulders, wherein the exterior pockets extend downwardly between the rib and corresponding portions of the front and rear walls, andwherein the front and rear walls each have a curved portion having a curvature causing the distance between the front and rear walls to decrease as the curved portions extend upwardly away from the bottom wall and toward the top wall, wherein the curved portions of each of the front and rear walls extend outwardly from a first vertical plane bisecting the compactor wheel tip from front to back at a pocket angle Φ with respect to a line perpendicular to the first vertical plane such that the distance between the front and rear walls increases as the front and rear walls extend outwardly from the first vertical plane toward the side walls. 5. A compactor wheel tip according to claim 4, wherein the front and rear walls each have generally vertical top portions disposed between the top wall and corresponding curved portions, and wherein the top portions of the front and rear walls extend outwardly from the first vertical plane toward the side walls with the same pocket angle Φ as the curved portions. 6. A compactor wheel tip according to claim 4, wherein the front and rear walls each have generally vertical bottom portions disposed between the bottom wall and corresponding curved portions, and wherein the bottom portions of the front and rear walls extend outwardly from the first vertical plane at a draft angle Δ with respect to a line perpendicular to the first vertical plane such that the distance between the front and rear walls decreases as the front and rear walls extend outwardly from the first vertical plane toward the side walls. 7. A compactor wheel tip according to claim 4, wherein portions of the ground engaging surface defining the shoulders are higher with respect to the bottom wall than a portion of the ground engaging surface defining the rib. 8. A compactor wheel tip according to claim 7, wherein intersecting portions of the top wall and the front and rear walls proximate the exterior pockets define upper edges of the respective exterior pockets, and wherein the portion of the ground engaging surface defining the rib is higher with respect to the bottom wall than the upper edges of the exterior pockets. 9. A compactor wheel tip according to claim 4, wherein the side walls extend outwardly from a second vertical plane bisecting the compactor wheel tip from side to side at a draft angle Δ with respect to a line perpendicular to the second vertical plane such that the distance between the side walls decreases as the side walls extend outwardly from the second vertical plane toward the front and rear walls.
