Ours is a lower end GE electric. It goes up to 550°F.
I do use baking tiles which are the same material as most pizza stones.
View attachment 1028428I have a couple of stones as well but can make a little bit bigger pizza with the tiles.
I set it to 510° for yesterday's bake and the bottoms came out well,

I didn't time the bakes because this oven takes longer to achieve similar results to the old one. (not just with pizza)
My early tries had trouble getting a good brown on the bottom so I gave up timing them and just go by visual progress.
I have been having better results with all my baking more recently so maybe the heating elements needed to break in - not sure if that is a thing but it's all I can come up with.
