EZ use WD40

why did you ever put the double sided tape in the first place?! ............................ok i'll help ya. solution- just rub peanut butter on it and slowly peel it off. -peanut butter has some kind of oil in it to help remove sticky substance.

Goo Gone is my remover of choice, really anything oily should work. Just make sure it won't stain the tile.

Use the peanut butter trick. WD 40 is and oil based product and can stain ( permanently) and not sure whats in goo gone. I m assuming this is a vinyl floor tile and not ceramic. If ceramic you can use the other product being careful not to get it on the grout lines. But the natural oils in PB do work on the type of stuff.GL

If Goo Gone doesn't do the job, try Goof Off (provided the floor tiles are ceramic. DO NOT use Goof Off if they're vinyl tiles)
