A tire includes a tread reinforcing layer. The tread reinforcing layer includes a ply reinforcing portion in which belt-shaped plies are wound. The ply reinforcing portion includes a lattice-shaped portion in which a plurality of the first inclined portions and a plurality of the second inclined portions intersect with each other such that side edges of the first inclined portions and side edges of the second inclined portions do not contact with each other so as to have space portions between them. Each of the first inclined portions and the second inclined portions has an angle with respect to a tire circumferential direction continuously decreased from an inner side in a tire axial direction to an outer side in the tire axial direction.
