Abstract
In my pneumatic tire, a circumferential belt is formed by a spirally wound band strip, the tread includes at least three circumferential land portions, cords of the inclined belt layer are steel cords, the total cross-sectional area of the steel cords per 25 mm of width perpendicular to the extending direction of the steel cords is from 2.3 to 4.0 mm2, a gap is present in the tire width direction between each lap of the band strip, and the relational expression W/{(w+2d)+0.3×w}≥1.0 is satisfied, where W is the width in the tire width direction of the circumferential land portion with the smallest width among the circumferential land portions, w is the width of the band strip in the tire width direction, and d is the width of the gap in the tire width direction between each lap of the band strip.
