The present invention is to provide a flexible polyurethane foam for tires that can effectively suppress damages, such as chips and cracks, and deformation, such as compression (permanent set in fatigue), even when attached to an inner face of a tire by using a band member. A flexible polyurethane foam for tires 5 which is attached to a gap between a tire and a wheel rim, wherein a density is in the range from 7 to 40 kg/m3 and a tear strength (N/cm) per unit density (kg/m3) is 0.30 or more, a noise reducing device with the flexible polyurethane foam for tires 5 fixed to a ring-shaped band member, and a tire 10 with the noise reducing device attached thereto.
