Based on past experience and several failed attempts, there could be a couple things at play. After the stone is fully heat soaked, I usually find that at 500-550, the pizza needs a good 8-12 minutes to finish. If the top is cooking too fast and the crust too slow, adjust the vents to turn the heat down.
For the food science nerds like me, dough recipe also plays a big part in the perfect pizza. Because it’s ground more finely than normal bread flours, “00” flour tends to absorb more water. With a higher water content, I’ve found that it usually needs a higher temp (650-700) and shorter bake time. Some “00” pizzeria flours are formulated to be baked at over 700 degrees. This type of flour tends to result in tough and chewy dough at lower temps/longer bake times instead of tender and crispy. Now if your dough recipe contains sugar, it will quickly burn at the higher temps.
Hope this helps.
