Abstract
Official abstract text for this publication.
One embodiment relates to a tyre with a bead profile structure, comprising a tread, sidewalls, and beads 10 for improving lateral stiffness, wherein the bead ( 10 ) has a range in which the X-coordinate is 8.8-9.7 mm and the Y-coordinate is 19.2-21.7 mm from origin (O), which is a common European Tyre and Rim Technical Organization (ETRTO) rim standard reference point of a bead outermost point (P) that is in contact with a wheel rim.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tyre with bead profile structure, the tyre comprising: a tread, side walls, and beads, wherein each of the beads has a bead outermost point that is configured to have an X-coordinate at 8.8-9.7 mm and a Y-coordinate at 19.2-21.7 mm from a European Tyre and Rim Technical Organization (ETRTO) rim standard reference point, the bead outermost point being configured to be in contact with a wheel rim, wherein each of the beads comprises a lower bead portion at a bottom and an upper bead portion at a top based on the bead outermost point, wherein an outer curvature radius of the lower bead portion has a range of 30 to 100 mm, and an outer curvature radius of the upper bead portion has a range of 1000 mm to infinity (straight line). 2. The tyre of claim 1 , wherein the tyre is configured to have a section width extending to an outermost position of the tyre in a transverse direction when air is injected, such that the outermost position of the tyre protects the wheel rim and a rim guard that protects the wheel rim is not required. 3. The tyre of claim 1 , wherein an inner curved surface of the tyre at the bead outermost point of each of the beads has a curvature radius of 0.5 to 2 mm.
