    摘要： An object is to provide a pneumatic tire with enhanced on-snow performance. On-snow performance is enhanced due to a tire 10 having a tread 12 provided with a shoulder circumferential direction main groove 16 formed with alternating narrow groove-width portions 16A and wide groove-width portions 16B having a wider groove-width than the narrow groove-width portions 16A extending in the tire circumferential direction. The tread 12 is further provided with an intermediate lug groove 32, extending in a direction so as to intersect the shoulder circumferential direction main groove 16 and having a first end portion connected to the shoulder circumferential direction main groove 16. The intermediate lug groove 32 is provided such that one of the wide groove-width portions 16B is positioned on an extension line of the intermediate lug groove 32.

    摘要： There is provided a pneumatic tire sufficiently improving drainage performance, driving stability, uneven wear resistance and quiet performance. A pneumatic tire 1 has at least one tire circumferential groove 9 extending along the tire circumferential direction in a tread portion 2. In addition, there are provided in a surface of the tread portion, a plurality of inclined grooves consisting of two or more small grooves 10 inclined at the same direction with respect to the tire circumferential direction and having an inclination angle within a range between 10 degrees and 60 degrees and configured in a zig-zag manner by coupling ends of the small grooves 10. The inclined grooves 11 are included in any widthwise section of the tread portion 2 of the tire and a part of the inclined grooves 11 is opened to the tire circumferential groove 9.
