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.
