Latest Patents

Ohkoshi holds a patent for a heavy-duty pneumatic tire. This invention includes a tread, a pair of sidewalls extending substantially inward radially from the ends of the tread, and a pair of beads positioned substantially radially inwardly of the sidewalls. The design features a clinch portion that extends from the sidewalls to the beads. A concave curved surface on the outer surface of the clinch portion runs in a circumferential direction. Additionally, a convex curved surface formed on the radially outer side end of a rim flange is engageable with the concave curved surface. The ratio R/R of the curvature radius R of the concave curved surface to the curvature radius R of the convex curved surface of the rim flange satisfies the condition 1.7 ≤ R/R ≤ 2.5. The curvature radii R and R of the concave and convex curved surfaces, respectively, are each a radius of curvature of an arc on a cross-section taken along a plane including a tire center axis. This patent showcases Ohkoshi's innovative approach to tire design.
