I claim, the ornamental design for a textured tile surface, as shown and described.
FIG. 1 is a perspective view of the textured tile surface;
FIG. 2 is a front elevation view of the textured tile surface; and,
FIG. 3 is a broken away, cross-sectional view of the textured tile surface of the invention as taken along line 3-3 of FIG. 2, for the purpose of clarifying its shape.
The broken line showing of structure is for illustrative purposes only, and forms no part of the claimed design.
