The invention relates to the technical field of rubber production and specifically relates to a pneumatic rubber tire. The pneumatic rubber tire is characterized by being prepared from the following raw materials in parts by weight: 20-30 parts of butadiene styrene rubber, 20-30 parts of natural rubber, 4-5 parts of zinc oxide, 10-12 parts of carbon black, 4-5 parts of silicon dioxide, 2-3 parts of isoprene, 1-3 parts of cross-linking agent, 2-3 parts of sulfur, 3-5 parts of stearic acid and 1-2 parts of anti-aging agent. The Tg of the isoprene copolymer elastomer of the pneumatic rubber tire is at least 30 DEG C lower than the Tg of other elastomers based on diene. The cross-linking agent is divinyl benzene or stannic chloride.
