Will expansion and contraction cycles of a radiator mar the tile the radiator sits on?

Hello all;



I'm the proud and protective owner of a recently  renovated bathroom .  The bathroom is warmed by a 16-inch radiator, connected to a single pipe steam system.  The radiator sits directly on a new ceramic tile floor.  We chose tiles with a texture to lessen the risk of falls.



So, my concern is whether I should shod the 2 radiator radiator feet opposite the feed pipe with furniture glides to protect the tiles from the expansion and contraction cycles of normal heating.  Over time, won't the movement of the metal feet against the brittle ceramic surface act like a file and dig down into the tiles?



Is there a  product more appropriate to the hot metal feet of radiators  than plastic  furniture glides?  I imagine that some sort of radiator 'shoes' on the vent-side radiator feet would be beneficial is tipping the radiator back towards the feed pipe and helping the condensate to return to the boiler.  But the shoes should deal with the heat and  weight of the radiator over years of service.



Thank you for your advice,

George
