Ernie,
You saw mine and I have been jacking cars up on that lift and just jacking them up since I put it in and never had a place show in the tile, I did replace one once that I dropped my propane torch on and it melted a place before I could get it off. But that only took abut 45 seconds as it was at the very edge. Just popped that tile out and put in a new one. I have also used jack stands on mine with no visible damage. And No, I don't get anything for telling you this.
Ron
