Any idea what causes a tile to "pop" when you step on it? I have one tile in a bathroom that will pop when you step on it in the winter, in the summer it stops. Now, during summer, a separate tile in another part of the bathroom pops when stepped on, but that one stops in the winter. It is porcelain tile with cement backerboard underneath and a plywood subfloor.
