I am guessing that the tile wants to be a little smaller than the trays, in order to let air circulate around the bottom heating elements. I have the Kaiser convection oven.
Yeah, I intentionally left a little space all around. BTW, get 2-3 tiles if you can. Putting in several acts as a heat sink (and you have a spare in case you break one). Although it takes a bit more time to heat up, the oven retains more heat when you open the door. Heat dropping when you open the door is a problem for small ovens.
Unfortunately my bottom stone cracked (all by itself) last night (I baked 8 boules). But it's not a big deal; the pieces fit together seamlessly and the top stone is uncracked (so far). I didn't get a great bottom crust with the current setup, though, so now I'm trying just one stone, set lower.
