The invention relates to a composition for reducing noise of a wheel and the noise-reducing wheel. The composition for reducing noise of the wheels comprises 100 parts of combined polyether PHR, 15 to 28 parts of foaming agent PHR, 130 to 160 parts of polyisocyanate PHR, 10 to 30 parts of surfactant PHR, 20 to 80 parts of foam stabilizer PHR, 40 to 80 parts of viscosity modifier PHR, 1 to 8 parts of Ca (OH) 2 PHR or 5 to 15 parts of Na2CO3 PHR, 90 to 100 parts of deionized water PHR and 2 to 4 parts of silane coupling agent PHR. According to the composition for reducing noise of the wheel, the noise reduction effect of the wheel in a cavity frequency band can reach 8-12dB.
