More Information
Summary:A pneumatic tire includes a ply having a plurality of cords each having an average cord diameter D, and a sidewall rubber having a loss tangent tan δ The plurality of cords each includes a plurality of filaments twisted together, the plurality of filaments each having an outer diameter d. The plurality of cords each has a ratio D/d of the average cord diameter D to the outer diameter d being equal to or more than 28. The ratio D/d and the loss tangent tan δ of the sidewall rubber satisfy the following formula;(tan δ)/(D/d)*1000≤5.5.
