<p>PROBLEM TO BE SOLVED: To provide a tire that is improved in side-cut proof property.SOLUTION: The tire includes: a pair of beads; a pair of side-walls extended on the radial outside of the bead; a tread bridged between both side-walls; and a carcass constituted of at least one layer of a carcass ply extended from one bead to the other bead through the tread. In the tire, a side wall region S that is held between a position of 0.5 times of the tire sectional height distant from a bead base line of the tire and a position of 0.9 times of that includes a region (a) where a ratio t/w of a thickness t between the external surface of the side wall and the carcass to the whole thickness w of the side wall is 0.3 or more and 0.6 or less, and the region (a) occupies at least 10% or more of the region S.</p> |
