The floor in our dining room is tile and I'm tired of changing the felt pads on the chairs. The grout lines on the felt pads are very stiff and the chairs have always been a bit lower in relation to the table, so I decided to try casters instead. They were easy to install with a little drilling, they are very strong and well made and roll very easily along the grout lines in the tile. I wish I had done this many years ago.
