The invention relates to a low-rolling-resistance pneumatic tire, and the low-rolling-resistance pneumatic tire is provided with a tread, and a circumferential groove is formed in the tread; each circumferential groove is provided with a notch groove, a thin groove and a water storage groove which are sequentially formed from the tire surface to the interior of the tire body; the maximum widths of the notch groove, the thin groove and the water storage tank in the axial direction of the tire are marked as W1, W2 and W3 respectively, and at least W2lt is met; w1 and W2lt; w3. According to the low-rolling-resistance pneumatic tire, the three-section groove design of the notches, the thin grooves and the water storage grooves is adopted in the radial direction of the tire through the central circumferential groove, and parameters such as the width, the depth and the repeated spacing are reasonably configured for the three-section groove design, so that it is ensured that the tire has excellent wet land performance, low-rolling-resistance performance and stone clamping prevention performance.
