Latest Patents

Shingo Umekita holds a patent for a pneumatic tire that features a unique design. The patent describes a tire in which fillers are layered over clinches in portions outward of a carcass in the axial direction. The carcass ply is turned up around cores, and the turned-up portions are strategically disposed between the fillers and apexes. Each clinch has a maximum thickness Tcx that is measured along a line normal to an inner surface, in the axial direction, of the clinch. The design specifies that the ratio of the thickness T of the filler to the sum of the thickness T and the thickness Tcx is greater than or equal to 0.1 and not greater than 0.6. Additionally, the percentage of a complex elastic modulus E*f of the filler relative to a complex elastic modulus E*a of the apex is greater than or equal to 70% and not greater than 125%. This innovative approach aims to improve tire performance and longevity.
