摘要:
This disclosure aims to achieve reduction in rolling resistance and ensure excellent steering stability. In this disclosure, a tire widthwise maximum width of a carcass is 1.35W or less; a tire outer surface has a recess; within a second height range h2 and on the outer side in a tire radial direction with respect to bead cores, a radius of curvature of the carcass is 0.46h or more; within a third height range h3, the radius of curvature of the carcass is 0.62h or more; during movement of a virtual point from a bead core height position Hbc toward a third height position H3, a tire gauge at the virtual point is reduced by a reduction amount of 0.025×G0/mm or less; and the tire gauge at the virtual point at the third height position H3 is 10% or more of the tire widthwise maximum width of the bead core.
