Abstract: An outer diameter of a pneumatic tire 350 mm or more and 600 mm or less. As RW is defined by a rim width of a rim wheel assembled to the pneumatic tire and SW is defined by a tire width of the pneumatic tire, the relation of 0.78≤RW/SW≤0.99 is satisfied. A carcass has a carcass cord arranged along the tire width direction. The carcass cord is formed of a filament of steel. The outer diameter of the carcass cords is 0.7 mm or less, and a distance between adjacent carcass cords is 4.0 mm or less.
