Igniro2,
Based on the additional information you have provided, I can see that your dough recipe is a "bare bones" recipe, using only flour, water, yeast and salt. Although the yeast levels and hydration (the ratio of the weight of water to the weight of flour) seem adequate to support good lift in the dough, I can see how it might bake up as quite crusty and chewy, much like a crusty French bread made from the exact four ingredients.
My suggestion is to add some oil and sugar to the dough. Both will help provide a short and tender crust. I would recommend that you start with about 5% oil (as a percentage of the weight of flour) and 2% sugar. Since you are working in volume measurements, it is a bit difficult to be accurate in the quantities, but I estimate that 5% oil in your recipe comes to about 5 teaspoons. For the sugar, 2% comes to about 2 1/3 teaspoons. I would add the sugar along with the salt in your dough making process, or just dissolve both in the water before adding the yeast (I assume you are using active dry yeast, which should be hydrated first in a small amount of warm water for about 10 minutes before adding it to the main water and the rest of the ingredients). I would add the oil after all the other ingredients have been combined and kneaded together, to avoid interfering with the hydration of the flour.
If you decide to use sugar in the crust and bake the pizza directly on the pizza stone, it is possible that you may experience premature or excessive bottom crust browning. At the levels recommended (2%), this shouldn't be a problem in a home oven setting, but if you do experience premature or excessive browning, you may want to decrease the sugar or eliminate it entirely the next time. Alternatively, you can put the dressed pizza on one or two pizza screens and place the screen(s) directly on the stone. The screen(s) will provide a barrier between the pizza and the stone and allow the pizza to bake more slowly (a longer bake time) and avoid the excessive browning. If you'd like, you can also "deck" the pizza, by removing the pizza screen(s) and letting the pizza sit directly on the stone and get increased bottom crust browning directly from the stone. This is a common approach used by professional pizza operators with commercial deck ovens under similar circumstances. Using both oil and sugar should also naturally speed up the bake of the pizza and prevent the crust from becoming too crispy (or dark) because of overbaking. As with any home pizza baking exercise, you may have to do some experimenting with the dough formulation and oven temperature and bake time to "marry" your pizza dough with your particular oven.
I estimate that your recipe produces about 27 ounces of dough. You didn't indicate the type of pizza you are making (American?) or how many and their size. However, these factors will also influence the final results you get.
Good luck.
