Abstract

PURPOSE:To reduce stress shared by a belt layer so as to enhance the durability of a belt portion by forming a carcass line installed in a normal rim in the cross section of the radial directions at the time of filling up normal internal pressure to satisfy a specific dimension relation. CONSTITUTION:It is respectively presumed that a maximum height from the rim diameter of a carcass line is H, the maximum width of the carcass line is B, a maximum clearance between a straight line which is parallel with the rotation shaft of a tire on a radial cross section and crosses with the carcass line at two points and as well the distance L between cross points satisfies that L=0.96B-0.77H, and the carcass line is (a), a rim width is J, and the width of an area in which the cord 30a of a belt layer 30 crosses is 1. At this time, the configuration of the carcass line is set so as to satisfy the following respective equations. Namely, 0.45<=H/B<=0.75. (-0.12H/B)+0.79<=l/B<=(-0.12H/ B)+0.85. (0.1H/B)+1.11<=B/J<=(0.1H/B)+1.15. O<a/H<=0.017.
