Abstract
Provided is a pneumatic tire that can be obtained without requiring complicated design and has improved noise performance. On the inner vehicle-mounting side, the circumferential pitch length of the tire has pitch variation comprising at least three pitch lengths and, if the number of pitches is n and the pitch lengths (Pi) are Pi1, Pi2, Pi3, . . . , Pin, in order from the greatest pitch length, the pitch lengths satisfy the relationships Pi1/Pi2≤Pi2/Pi3≤ . . . ≤Pin−1/Pin, and Pi1/Pi2.
