  • Pneumatic tire
    Patent number: 10759233
    Abstract: In the tire 2, fillers 10 are layered over clinches 8 in portions outward of a carcass 14 in the axial direction. A carcass ply 50 is turned up around cores 44. Turned-up portions 50a are disposed between the fillers 10 and apexes 46. Each clinch 8 has a maximum thickness Tcx that is measured along a line normal to an inner surface, in the axial direction, of the clinch 8. A ratio of a thickness Tf1 of the filler 10 to a sum of the thickness Tf1 and 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 filler 10 relative to a complex elastic modulus E*a of the apex 46 is greater than or equal to 70% and not greater than 125%.
