Title:
PNEUMATIC TIRE FOR HEAVY LOADS
Document Type and Number:
WIPO Patent Application WO/2013/094300
Kind Code:
A1
Abstract:
A tire (1) is provided with a tread (2), a pair of side walls (3) extending roughly inward in the radial direction from the edges of the tread (2), a pair of beads (4) positioned roughly inward in the radial direction relative to the side walls (3), and clinch parts (5) positioned so as to extend from the side walls (3) to the beads (4), wherein a concave curved surface (21) with which a convex curved surface (22) formed on the outer edge in the radial direction of a rim flange (30) can engage is formed on the outer surface of the clinch parts (5) so as to extend in the circumferential direction, the ratio of the curvature radius (R1) of the concave curved surface (21) relative to the curvature radius (R) of the convex curved surface (22) on the rim flange is 1.7≤R1/R≤2.5, and the curvature radius (R1) of the concave curved surface (21) and the curvature radius (R) of the convex curved surface (22) are both the curvature radius of an arc in a cross-section that is cut at a plane including the tire central axis.
