Arrange the 4 (10-inch) tortillas (each cut into 8 wedges) in a single layer on a baking sheet, leaving space between wedges so they can crisp evenly.
Lightly spritz the tortilla wedges with olive oil spray on both sides.
In a small bowl, stir together 1/4 cup sugar and 1 teaspoon ground cinnamon until evenly combined.
Sprinkle the cinnamon-sugar mixture evenly over the tortilla wedges, turning or gently tossing the wedges so they are coated.
Bake the wedges on the baking sheet until lightly golden brown and crisp, about 10 minutes (watch closely near the end and rotate the sheet if needed for even browning).
Remove from the oven and let the chips cool on the baking sheet for a few minutes until crisp, then serve.
