ABSTRACT:
A pneumatic tire having a tread surface comprised of a plurality of pitches of different lengths arranged to extend around the circumference of the tire and which includes a pitch of the shortest pitch length P.sub.min and a pitch of the longest pitch length P.sub.max, a period of the pitches begins with a pitch of P.sub.min and contains at least one pitch of P.sub.max between the pitch of P.sub.min and a pitch of P.sub.min in a next period, a fundamental period begins with the pitch of P.sub.min and ends with a pitch located immediately before the pitch of P.sub.min located first in the next period. In a pitch arangement within the fundamental period, the proportion of components of each higher order in the range of a second order to a fourth order relative to the first-order component is 80 to 200% when Fourier expansion of a stepped waveform comprising the reciprocal of the pitch length and the pitch length is conducted. The number of the fundamental periods is 1 to 4. The length of the pitch arrangement is 60% or more of the total circumferential length of the tire. The length of each fundamental period is at least 1/7 of the total circumferential length of the tire.
