Abstract
In a pneumatic tire, a difference Gs−Ge falls in a range of Gs−Ge≧0.10, where Gs is a groove area ratio for a wear rate 0% and Ge is a groove area ratio for a wear rate 100%. Further, a groove area ratio G for a wear rate 20% falls in a range of (Gs−G)/(Gs−Ge)≧0.30, and a groove area ratio G for a wear rate 35% falls in a range of (Gs−G)/(Gs−Ge)≧0.50.
