Abstract
A tire comprising: a carcass; and inclined belt layers and a circumferential belt layer, 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 Wof an inclined belt layer having a widest width and a tire widthwise width Wof an inclined belt layer having a narrowest width satisfy a correlation that W≤0.6W.
