This disclosure is to provide a tire having increased cornering power and reduce load dependence thereof. A tire comprising: a carcass toroidally extending between a pair of bead portions; and inclined belt layers having cords inclined with respect to a tire circumferential direction and a circumferential belt layer having cords extending along the tire circumferential direction, the inclined belt layers and the circumferential belt layer being disposed on a tire radial outer side of a crown portion of the carcass, wherein: the circumferential belt layer satisfies a correlation that X‰¥750 when it is defined that X=Y×n×m, where Y is a Young's modulus in GPa of the cords forming the circumferential belt layer, n is a number of the cords implanted per 50 mm of width, and m is a number of layers of the circumferential belt layer; the inclined belt layers comprise at least two inclined belt layers having different tire widthwise widths; and a tire widthwise width W 1 of an inclined belt layer having a widest width and a tire widthwise width W 2 of an inclined belt layer having a narrowest width satisfy a correlation that W 2 ‰¤0.6W 1 . |
