Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2014/162732
Kind Code:
A1
Abstract:
The tread of a pneumatic tire is provided with: at least one tilted belt layer which is formed by covering cords with rubber, the cords being arranged parallel to each other and extending tilted relative to the circumferential direction of the tread; and at least one circumferential belt layer which is located on the inside of the tilted belt layer in the radial direction of the tire and which is formed by covering cords with rubber, the cords being arranged parallel to each other and extending in the circumferential direction of the tread. The treading surface of the tread is provided with: circumferential grooves which extend in the circumferential direction of the tread; and shoulder-side land sections which are each defined between each of the outermost circumferential grooves in the width direction of the tire and the corresponding one of the ground contact ends of the tread. The pneumatic tire is characterized in that positions on the treading surface of the tread, the positions corresponding to the outermost ends of the circumferential belt layer in the width direction of the tire, are located within the shoulder-side land sections, and in that the distance, measured in the width direction of the tire, between each of the outermost ends of the circumferential belt layer in the width direction of the tire and the tire equator-side end of the corresponding one of the shoulder-side land sections is in the range of 12% to 22%, inclusive, of the half the width of the circumferential belt layer in the width direction of the tire.
