Abstract

A tire includes: a ring shaped tire frame member that is made of a resin with plural tire pieces joined along a tire circumferential direction; a joint portion reinforcing belt that is adhered to the tire frame member, that extends around the tire circumferential direction, and that covers a joint portion of the plural tire pieces; and a tread layer that is provided further to the tire radial direction outside than the tire frame member and the joint portion reinforcing belt.

First claim

The invention claimed is:

1. A tire comprising:
a ring shaped tire frame member that is made of a resin with a plurality of tire pieces, the plurality of tire pieces being adjacent to each other in a tire axial direction and being joined along a tire circumferential direction;
a joint portion reinforcing belt that is adhered to the tire frame member, that extends around the tire circumferential direction, and that covers a joint portion of the tire pieces; and
a tread layer that is provided at a tire radial direction outside of the tire frame member and the joint portion reinforcing belt; wherein:
the tire frame member includes a pair of bead portions, a pair of side portions that extend from the pair of bead portions toward the tire radial direction outside and that are disposed around the tire circumferential direction, and a crown portion that couples the pair of side portions together; and
side reinforcing members that are embedded in the side portions at intervals around the tire circumferential direction so as to intersect the tire circumferential direction on progression from the bead portions toward the crown portion.

2. The tire of claim 1 , wherein
the joint portion reinforcing belt is provided at the tire radial direction inside of the tire frame member.

3. The tire of claim 1 , wherein:
facing end faces of the plurality of tire pieces are joined together by a joint member made of resin; and
the joint portion reinforcing belt covers the joint member from the tire radial direction outside.

4. The tire of claim 1 , wherein:
the side reinforcing members extend as far as a tire axial direction center portion; and
when the joint portion reinforcing belt is projected along the tire radial direction, both width direction end portions of the joint portion reinforcing belt overlap the side reinforcing members.
