  "textContent": "A pneumatic tire has a tread portion including a tread rubber forming a ground contact surface, a belt layer, and an outer diameter from 350 to 600 mm, and is configured to be mounted on a tire rim having a rim width RW from 78% to 99% of a tire section width SW of the pneumatic tire. The ground contact surface is divided into a plurality of land regions including shoulder land regions by circumferential grooves provided in the tread portion. In an axial half of the pneumatic tire, the shoulder land region has an inner edge located axially inside an outer edge of the belt layer, and a distance LA between the inner edge and the outer edge is from 10% to 30% of a maximum belt width WA of the belt layer. A hardness Hs of the tread rubber satisfies Expression 1: Hs≤75−20×LASW",
