Abstract
In the tire, fillersare layered over clinchesin portions outward of a carcassin the axial direction. A carcass plyis turned up around cores. Turned-up portionsare disposed between the fillersand apexes. Each clinchhas a maximum thickness Tcx that is measured along a line normal to an inner surface, in the axial direction, of the clinch. A ratio of a thickness Tfof the fillerto a sum of the thickness Tfand the thickness Tcx is greater than or equal to 0.1 and not greater than 0.6. A percentage of a complex elastic modulus E*f of the fillerrelative to a complex elastic modulus E*a of the apexis greater than or equal to 70% and not greater than 125%.
