The invention discloses a pneumatic tire which improves dry land performance, wet land performance and eccentric-wear-resistant. A pneumatic tire (1) includes a tread portion (2) including an inboardtread region between a tire equator (C) and an inboard tread edge (Te1), and an outboard tread region between the tire equator (C) and an outboard tread edge (Te2). The inboard tread region is provided with a first main groove (11) extending and a second main groove (12) each extending continuously in the tire circumferential direction. The outboard tread region is provided with a plurality of recesses (15) that are not in communication with other grooves. The recesses include a plurality of deep bottom recesses (16) having depths equal to or more than 5 mm. A total of opening areas of the deep bottom recesses (16) on a ground contact surface of the tread portion (2) is equal to or less than 5% of a surface area of the outboard tread region that is obtained by filling up all grooves and recesses provided thereon.
