Zusammenfassung:	The invention discloses a formula of a tread of a low-rolling-resistance tire and a preparation method thereof. The formula of the tread of the low-rolling-resistance tire comprises the following components: 10-20% of natural rubber, 10-20% of polybutadiene rubber, 20-40% of solution polymerized styrene butadiene rubber, 20-40% of high-dispersion white carbon black, 0.5-1% of a peptizer A-8, 1-2% of a chemical anti-aging agent 6PPD, 1-2% of a physical anti-aging agent microcrystalline wax, 1-3% of an active agent ZNO, 1-3% of an active agent SA, 1-3% of polyethylene glycol PEG, 1-3% of a vulcanizing agent S-325, 1-3% of an accelerant NS, 0.1-0.8% of a special accelerant CTP and 4-8% of a coupling agent SI69. The formula of the tread of the low-rolling-resistance tire has the beneficial effects that the rolling resistance of the tire is low and can reach an A level or a B level, various physical and mechanical properties of the tire are basically consistent to those of a tire having non-low rolling resistance,
