Abstract
A plurality of shallow grooves which are shallower than a sipe are formed on land sections formed on treads of a pneumatic tire. The shallow grooves are configured so that a total sectional area of the shallow grooves per unit area in a cross section in a tire width direction in at least one of tread end areas arranged at end sides of the tread surface in the tire width direction or land end areas arranged at portions adjacent to a drain main groove on the land sections becomes larger than a total sectional area of the shallow grooves per unit on the other areas.
