ABSTRACT:
A pneumatic tire having a tread pattern formed on the surface of the tire by using at least two types of main pattern elements having a length in the circumferential direction of the tire equal to at least 1.0% of that of the outer periphery of the tire and a subpattern element having a length in the circumferential direction of the tire of at least 0.5 mm and equal to 0.6% or less of that of the outer periphery of the tire, combining one of the main pattern elements with the subpattern element to prepare a plurality of types of combination pattern elements different from each other in the length of the circumferential direction of the tire and the pattern, and periodically disposing these pattern elements along the circumferential direction of the tire.
