If they are the same grey/white speckled, industrial grade, ones I had in the GT they most likely are.
Also, if like the ones I had, they are probably coming off by themselves.
Obviously, to be on the safe side, make sure to use a well fitting dust mask when you take them off and put them in a heavy duty contractor trash bag.
If you have to scrape any remaining bits off the floor I believe they suggest that you moisten down the surface to prevent dust from spreading. Mine popped right off just leaving some old adhesive.
Some states have a disposal policy requiring bureaucratic interference. I won't tell if you won't.
