Title:
Pneumatic tires
Document Type and Number:
Japanese Patent JP6315667
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tire which can unite rolling resistance and durability, and rim-removal resistance.SOLUTION: A groove 28b extended in the circumferential direction is formed on a shoulder region S of a tire 2. A band 14 includes a full band 40 and a pair of edge bands 42. The edge band 42 is extended from 10 mm or more inner side in the axial direction from bottom of the groove 28b to the outer edge in the axial direction of a belt 12. Thickness Ta of a tread 4 in an equatorial plane, thickness Tb of the tread 4 on an edge part in the axial direction of the belt 12 and thickness Tc from the surface of a wing 20 to the surface of a carcass 10 on a position passing through an outer edge Pt in the axial direction of the tread 4 satisfy the following numerical relation: 0.5≤(Tb/Ta)≤1.0; 0.4≤(Tc/Ta)≤0.8.
