The invention discloses a rubber composition for treads of prick resistant loading radial tires, and belongs to the technical field of rubber tires. The rubber composition comprises the components in parts by weight: 100 parts of rubber, 4.0-8.0 parts of an active agent, 25-45 parts of carbon black, 5-20 parts of white carbon black, 0.1-4.0 parts of a silicane coupling agent, 1.0-3.0 parts of an accelerant, 3.0-6.0 parts of an anti-aging agent, 1.0-2.0 parts of a vulcanizing agent, 0.1-0.3 part of an anti-scorching agent, 0.1-3.0 parts of hydrocarbon resin, and 1.0-3.0 parts of a processing agent. All the raw materials can be used for manufacturing the rubber composition which has better cutting resistant performance and is applied to the treads of the prick resistant loading radial tires within a matching ratio range. For the rubber composition prepared by the invention, the strength, the modulus, the elongation and the like of the rubber materials of the treads can be improved, and the prick resistance, the cutting resistance and the like of the tires are improved.
