Abstract
A pneumatic tire includes a strip member which extends in a tire circumferential direction, with both ends thereof reaching each bead portion, and a belt layer disposed in a tread portion on an outer side in the tire radial direction of the strip members. The strip members are divided in the tire width direction, with each of the divided strip members having joints that join in the tire circumferential direction. The relative positions of the joints are disposed at less than 20° in the tire circumferential direction within the region of the maximum width TW in the tire width direction of the belt layer.
Claims17
A pneumatic tire comprising:
- a strip member, which extends in a tire circumferential direction, both ends thereof in a tire width direction reaching each bead portion;
- and
- a belt layer disposed in a tread portion on an outer side in a tire radial direction of the strip member;
- the strip member being divided in the tire width direction in the tread portion region into first and second divided strip members;
- the first and second divided strip members having joints that join in the tire circumferential direction;
- and
- relative positions of the joints of the first and second divided strip members, which are opposite each other in the tire width direction, being disposed at less than 20° in the tire circumferential direction within a region of a maximum width in the tire width direction of the belt layer, wherein spacing between the joints of the first divided strip member is non-uniform and spacing between the joints of the second divided strip member is non-uniform.
