PROBLEM TO BE SOLVED: To provide a tire particle aggregate capable of sealing a damaged part more surely, and recovering an inner pressure required for traveling after damage at an early stage. SOLUTION: This tire particle aggregate 100 is an aggregate of a tire 1 and a plurality of hollow particles 4. A side rubber 9 constituting a side wall SW comprises an inner side rubber 9a positioned at least on the inner side of a tread width direction, and an outer side rubber 9b positioned on the outer side of the tread width direction. The outer side rubber 9b has a tangent lossα(tanδ) in 1% load of 0.05-0.12 and a tangent lossβ(tanδ) in 3% load of 0.35-0.50. The hollow particle 4 is made of resin continuous phases and independent bubbles having an approximately spherical shape, and is expanded by reaching to a re-expansion starting temperature (Ts2) when the inner pressure of a tire air space 3 is lowered.
