A modular tile configured to interlock with multiple tiles to form a modular floor covering over a floor. The tile includes a top surface having a periphery defining side walls extending downward from the top surface, the side walls having a coupling portion configured to couple with other tiles adjacent thereto to form the modular floor covering. The tile also includes a bottom side, opposite the top surface, having a support grid including an array of downward extending polymeric post structures, at least some of the post structures including at least one resilient end portion with a radial end surface configured to be positioned against the floor to facilitate controlled deflection of the post structures. The post structures may comprise primary and secondary post structures, with the secondary post structures limiting the deflection of the primary post structures.

What is claimed and desired to be secured by Letters Patent is: 1. A tile configured to form a floor covering over a floor, said tile comprising: a top surface having a periphery defining side walls extending downward from the top surface; and a bottom side, opposite the top surface; and an array of support structures, each being load bearing and each extending from said bottom side, at least some of the support structures comprising deflecting primary support structures that deflect under a threshold load, and at least some of the support structures comprising different height secondary support structures that limit the deflection of the deflecting support structures. 2. The tile of claim 1, wherein the deflecting support structures comprise a resilient end portion configured to resiliently deflect against the floor with a load being placed above the support structures to the top surface. 3. The tile of claim 2, wherein the resilient end portion is configured to resiliently deflect against the floor to provide an upward spring force. 4. The tile of claim 2, wherein the resilient end portion is configured to suspend the side walls of the tile above the floor. 5. The tile of claim 2, wherein the resilient end portion extends from an upper portion of the deflecting support structures, the upper portion extending from the bottom side of the tile and configured to support the top surface of the tile. 6. The tile of claim 2, wherein the resilient end portion deflects in a bi-lateral direction. 7. The tile of claim 2, wherein the resilient end portion in the array of support structures deflects between a first bi-lateral direction and a second bi-lateral direction between respective adjacently positioned support structures. 8. The tile of claim 7, wherein first bi-lateral direction is transverse to the second bi-lateral direction. 9. The tile of claim 2, wherein the resilient end portion comprises an elongated width to facilitate the resilient end portion to resiliently deflect in a bi-lateral direction. 10. The tile of claim 2, wherein the at least one resilient end portion comprises two end portions extending downward from each of the post structures. 11. The tile of claim 2, wherein the resilient end portion comprises a tapered end portion configured to resiliently deflect with a load being placed above the support structures on the top surface. 12. The tile of claim 2, wherein the resilient end portion comprises a projection configured to resiliently deflect with a load being placed above the support structures on the top surface. 13. The tile of claim 1, wherein the deflecting support structures comprise a radial end surface is configured to induce a resilient end portion to slide and deflect laterally with a load being placed on the top surface. 14. The tile of claim 1, wherein the side walls have a coupling portion configured to couple with other tiles adjacent thereto to form a modular floor covering. 15. The tile of claim 1, wherein the bottom side comprises a support grid. 16. A modular floor tile system comprising: a floor; a floor tile adapted for placement about said floor, said floor tile comprising: a top surface configured to receive and distribute a load, and to deflect under said load; side walls extending downward from said top surface and defining a periphery of said tile; a bottom side opposite said top surface; a plurality of load bearing primary post structures extending downward from and arranged about said bottom side, said primary post structures including at least one end portion configured to be in continuous contact with the floor, and to facilitate deflection of said top surface in response to said load; and a plurality of load bearing secondary post structures also extending downward from said bottom side and interspaced with said primary post structures, said secondary post structures having a different height than said primary post structures, and including at least one end portion configured to contact said floor and support said top surface only upon said deflection of said primary post structures, said secondary post structures limiting said deflection of said primary post structures and said top surface. 17. The tile of claim 16, wherein said side walls comprise a coupling portion configured therewith to couple with other tiles adjacent thereto to form a modular floor covering. 18. The tile of claim 16, wherein said primary and secondary post structures are arranged about said bottom surface according to a pre-determined pattern. 19. The tile of claim 16, wherein said secondary post structures are activated and configured to displace to contact said floor upon said load being in excess of a pre-determined primary load threshold. 20. The tile of claim 19, wherein said pre-determined primary load threshold is between 100 and 300 pounds per square inch. 21. The tile of claim 19, wherein said primary post structures extend from said bottom surface a greater distance than said secondary post structures, wherein an end portion of said secondary post structures is located above said floor at loads below said primary load threshold. 22. The tile of claim 16, wherein said secondary post structures, upon activation, are configured to control and limit the deflection of said primary post structures. 23.
