Helter ,

I have been in construction most of my life , There are definately tile that are very tough and non skid , it is typically called "Quarry tile"it will hold up to almost any thing exept say dropping a #2 hammer on it, I dont know how well it would hold up to floor jacks over the long run either.another issue is the inherent unevenness of a tile job with its grouted joints, it could be a bit of a pain to move a car on a floor jack, or even your rollaway.
