Abstract
In a pneumatic tire including belt layers in a tread portion, the belt layers include a cross belt pair in which reinforcing cords constituting the belt layers intersect each other between layers, a distance between a tire outer surface and an end point of the cross belt pair measured in parallel to a line segment connecting a ground contact edge and an edge portion on the outer side of the outermost groove in the width direction on an outer surface of the tread portion satisfies 15 mm≤D1≤25 mm, a distance between the belt layer and a carcass layer at a position corresponding to an outer end point in an effective width of the cross belt pair satisfies 2.5 mm≤G1≤9.0 mm, and a ratio between a height Hα from a core separation point to a maximum outer diameter position of the carcass layer and a height Hβ to the maximum width position satisfies 0.55≤Hβ/Hα≤0.65.
