Abstract

A tire (1) is provided with a tread pattern (2) comprising a series of a number N of tread design units (4) arranged repeatedly and circumferentially of the tire in a sequence and having a number m of different circumferential lengths (L). A first pulse train (11) is defined by viewing the tread design units as pulses arranged in the same sequence as the tread design units at intervals which are defined by the circumferential lengths of the corresponding tread design units expressed in term of a ratio to one of the number m of different circumferential lengths. A maximum value Pmax of amplitudes P(k) (k = order from 1 to 2N) of frequencies obtained by Fourier transforming the first pulse train is limited to specific values. The amplitudes P(k) and P(k+1) of every two of the adjacent orders (k) and (k+1) do not satisfy a condition that both of the amplitudes P(k) and P(k+1) have values of 2/3 or more times the maximum value Pmax.
