<p>A pneumatic tire (30) comprising:
a tread (12);
a lug groove (14) extending from a shoulder side of said tread (12) toward a tire central plane (CL), the lug groove (14) being provided in plurality at said tread (12) in the tire circumferential direction (A) to form a lug pattern;
a recess portion (16) continuously provided in the tire circumferential direction (A) on the tire central plane (CL) of said tread (12); and
another recess portion (32) sequentially formed in the tire circumferential direction (A) in a center region (20) that extends in the tire circumferential direction (A) with a width that is 50% of the maximum width (W) of tire ground contacting portion so as to be symmetrical with respect to the tire central plane (CL) of said tread (12),
€ƒ€ƒ€ƒ wherein a negative ratio of the center region (20) other than said lug groove (14) is set to 10% to 25%.</p> |
