<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire for improving responsiveness by reducing a variation in cornering power, though adopting a pitch variation of changing the size of respective blocks in the tire circumferential direction. <P>SOLUTION: This pneumatic tire includes a tread pattern of changing a grounding width on the tire circumference, and largely constitutes the grounding width in a pitch as a pitch length of the block of a shoulder part becomes short, or the pneumatic tire includes two or more circumferential directional grooves. The pneumatic tire includes the tread pattern of changing the grounding width on the tire circumference, and largely constitutes the grounding width in the pitch as the pitch length of the block of a center part becomes short. <P>COPYRIGHT: (C)2013,JPO&INPIT |
