摘要： A pneumatic tire includes a tread portion provided with a series of design-cycles repeating in the circumference of the tire at variable pitches. The number (NP) of different kinds of pitches is at least 10. The variable pitches repeat increase and decrease alternately in one circumferential direction of the tire to define start design-cycles inclusive to the next start design-cycles from which the pitches start to increase. A series of design-cycles is composed of a series of units, each unit defined as a group of design-cycles starting from one of that start design-cycles inclusive to the next start design-cycle exclusive. The total number of units is from 4 to 20. The units consist of at least one first-unit, the number of which is 20 to 80% of the total number, at least one second-unit, the number of which is 20-80% of the total number, and optionally a third-unit, the number of which is 0 to 60% of the total number. The first unit is defined as including at least one pitch which is not less than a standard long pitch (PLa) and at least one pitch which is not more than a standard short pitch (PSa). The second unit is defined as including at least one pitch within one of the following two ranges, a range of not less than the standard long pitch (PLa) and a range of not more than the standard short pitch (PSa), but no pitch within the other range. The third unit is defined as all of the pitches therein more than the standard short pitch (PSa) and less than the standard long pitch (PLa).
