ABSTRACT:
To provide a pneumatic tire for a motorcycle in which both wear resistance and wet steering stability can be attained. Since a pair of zigzag circumferential direction grooves28are positioned at the center of a tread central region24C and has an amplitude, even when a certain camber angle is exceeded, an occurrence of a sudden separation of the zigzag circumferential direction groove28from a road-contact surface26can be prevented, whereby deterioration of wet steering stability can be suppressed. When the camber angle increases, water in a road-contact surface26is drained by inclining grooves32which are arranged at an external side of the zigzag circumferential direction groove28. Since sharp inclining groove portions32A of the inclining grooves32are positioned in the tread central region24C, and no lug groove components are employed, circumferential direction rigidities of land portions in the tread central region24C are high and exhibits excellent wear resistance. Since loose inclining groove portions32B and sub-inclining grooves38of the inclining grooves32are positioned in tread side regions24S, rigidities of land portions40resisting to inputs at the time of a large camber angle are high, and accordingly, wear resistance is high.
