A tire for a vehicle includes: a tread extending in a circumferential direction about a rotational axis of the tire; and wear indicators disposed in the tread and spaced apart from each other to be arranged in the circumferential direction. A harmonic noise signal caused by the tire when the tire rolls on a road surface to move the vehicle has neighboring first and second frequency peaks in a frequency spectrum of the harmonic noise signal, and the number of the wear indicators is in a range of 16 to 96 to generate, and when the tire rolls to move the vehicle at a speed in a target range, the wear indicators cause an additional frequency peak positioned between the first and second frequency peaks in the frequency spectrum when the tread is worn to reach a wear threshold.
