The only thing other than “air” that I have heard put into tires is nitrogen. That is done because pressure does not change as much with temperature change. You still need TPMS. If they put something like “slime” in the tires, I can only imagine how much they would need and the weight it would add. Me thinks someone is misrepresenting a product. I would find out what they put in and have it taken out. Just me. Then get a good TPMS like TST.
