The invention provides a tire apex composition, a tire apex and a preparation method of the tire apex, and relates to the technical field of tire manufacturing. The tire bead filler composition is prepared from the following components in parts by weight: 100 parts of raw rubber, 10 to 40 parts of modified carbon nanotube/carbon black aggregate, 1 to 12 parts of active agent, 0.8 to 6 parts of accelerant, 0.8 to 6 parts of vulcanizing agent, 3 to 7 parts of anti-aging agent, 0.5 to 4 parts of tackifying resin, 0 to 25 parts of white carbon black, 0 to 2.5 parts of silane coupling agent, 0 to 2.5 parts of protective wax and 0 to 0.3 part of scorch retarder, wherein the modified carbon nanotube/carbon black aggregate is obtained by carrying out high-temperature jet flow on a modifier and a carbon nanotube/carbon black aggregate. According to the invention, the modified carbon nanotube/carbon black aggregate is added into the tire apex composition, so that filler agglomeration is reduced, mechanical properties and wear resistance of the tire apex are improved, and heat generation of the tire apex can be further reduced.
