An apparatus and method for preventing debris from accessing and wrapping around the axles of a vehicle, such as a landfill compactor, are disclosed. The apparatus may include a wheel having a rim from which radially extend a plurality of cleats or tips. A subset of tips may be provided circumferentially around a laterally inner edge of the wheel. A wheel guard may be mounted between adjacent pairs of tips of the subset. Each wheel guard may be welded to the rim and to the adjacent pairs of tips. Each wheel guard may be a unitary piece of metal, or could be provided in two or more segment so as to be adjustable and thus facilitate use on wheels of differing diameters, or with different tip spacing. The wheel guards and adjacent tips form a continuous barrier around the circumference of the wheel to prevent debris from accessing and wrapping around the axles of the compactor.

1. A wheel guard for use on a compactor wheel having radially extending tips, comprising: an arcuate central beam having an upper surface, a lower surface, a first side, a second side, a first end, and a second end, the first and second ends having at least portions of which are complementarily shap
1. A wheel guard for use on a compactor wheel having radially extending tips, comprising: an arcuate central beam having an upper surface, a lower surface, a first side, a second side, a first end, and a second end, the first and second ends having at least portions of which are complementarily shaped with respect to the radially extending tips;a first flanking leg extending from the arcuate central beam lower surface; anda second flanking leg extending from the arcuate central beam lower surface, the first and second flanking legs extending away from the arcuate central beam in different directions. 2. The wheel guard of claim 1, further including a reinforcing material provided across at least a central portion of the arcuate central beam upper surface. 3. The wheel guard of claim 2, wherein the reinforcing material is provided across approximately one-third of the arcuate central beam upper surface. 4. The wheel guard of claim 1, wherein the arcuate central beam, first flanking leg and second flanking leg are formed as one, integral piece of material. 5. The wheel guard of claim 4, wherein the wheel guard is formed from a first segment and a second segment movable relative to each other. 6. The wheel guard of claim 5, wherein the first segment and second segment both include a recess and a tongue, the tongue of each segment being adapted to slide next to the recess of the other segment to adjust the length of the wheel guard. 7. The wheel guard of claim 6, wherein the first segment and second segment both include a shoulder defining an end stop to sliding movement and thus limit the dimension to which the wheel guard can be shortened. 8. The wheel guard of claim 5, wherein the wheel guard further includes end caps extending between the flanking legs and the arcuate central beam. 9. A compactor wheel, comprising: a rim having an annularly-shaped circumferential surface, an inner edge, and an outer edge;a plurality of tips radially extending from the annularly-shaped circumferential surface; anda plurality of wheel guards secured between circumferentially adjacent tips provided proximate the inner edge of the rim, the plurality of wheel guards and adjacent tips forming a barrier around the circumference of the rim, each of the wheel guards including a central beam, a first flanking leg and a second flanking leg. 10. The compactor wheel of claim 9, wherein each of the plurality of wheel guards includes two segments which are movable relative to each other prior to being permanently fixed in place. 11. The compactor wheel of claim 9, wherein each of the plurality of wheel guards includes hard facing only on a central section of each wheel guard. 12. The compactor wheel of claim 11, wherein the hard facing is applied over a range of approximately one-third to approximately two-thirds of the upper surface. 13. The compactor wheel of claim 9, wherein each of the wheel guards has a tip engaging end substantially mirroring the tip to which it is adjacent and does so along the entire length of the tip engaging end, but wherein the tip engaging end is only welded to the tip along a lower segment of the tip. 14. The compactor wheel of claim 9, wherein each of the wheel guards includes a substantially inverted “Y” shape in lateral cross-section. 15. The compactor wheel of claim 10, wherein the wheel guard further includes an end cap extending between the central beam and flanking legs proximate the rim. 16. A method of manufacturing a compactor wheel, comprising: providing a rim having an annularly-shaped circumferential surface, the circumferential surface having a laterally inner edge;mounting a plurality of tips to the circumferential surface, each of the plurality of tips extending radially away from the circumferential surface, a subset of the plurality of tips being circumferentially aligned around the rim and being proximate the lateral inner edge of the rim; andsecuring a wheel guard between circumferentially adjacent tips of the subset, the wheel guards and subset of tips forming a barrier around the circumference of the wheel, the wheel guard including a central section from which first and second flanking legs extend. 17. The method of claim 16 wherein each wheel guard includes an arcuate bottom surface and first and second ends, and wherein the wheel guards are secured by welding along the arcuate bottom surface and lower portions of the first and second ends, leaving a intersection between upper portions of the first and second ends and upper segments of the tips which are not welded. 18. The method of claim 16, further including adjusting the length of the wheel guards prior to securing the wheel guards. 19. The method of claim 18, wherein the adjusting is performed by sliding first and second segments of the wheel guards relative to each other along an expansion joint. 20. The method of claim 16 further including applying a hardened coating to a portion of an upper surface of each wheel guard.
