The invention provides a long-service life tire which is prepared from the following rubber raw materials in parts by weight: 30-80 parts of styrene butadiene rubber, 15-50 parts of oil-extended cis-1,4-polybutadiene rubber, 2-10 parts of natural rubber, 1-10 parts of styrene-butadiene rubber, 20-30 parts of butadiene rubber, 30-50 parts of carbon black-silicon dioxide mixture, 2-5 parts of zinc oxide and 1-8 parts of zinc stearate. 20-30 parts of rubber oil is filled in every 100 parts of styrene-butadiene rubber, and 25-35 parts of rubber oil is filled in every 100 parts of cis-1,4-polybutadiene rubber. By using the mixture of the styrene butadiene rubber, oil-extended cis-1,4-polybutadiene rubber, natural rubber, styrene-butadiene rubber, butadiene rubber and many other rubbers as the raw material matched with the carbon black-silicon dioxide mixture, the wearability of the tire is obviously enhanced, the service life is prolonged, and the tire has higher control stability and braking property.
