Abstract: A pneumatic tire includes a tread portion provided with a first shoulder main groove, a second shoulder main groove and at least one main groove to separate a first crown portion and a second crown portion. The first crown portion is provided with first crown sipes with a width less than 2 mm, but is not provided with any grooves with a width equal to or more than 2 mm. The second crown portion is provided with second crown sipes having a width less than 2 mm, but is not provided with any grooves with a width equal to or more than 2 mm. Each first crown sipe extends from the crown main groove to the first shoulder main groove with a first inclination direction. Each second crown sipe extends from the crown main groove to the second shoulder main groove with the first inclination direction.

Abstract: A pneumatic tire includes a tread portion provided with main grooves and land potions. The main grooves include an outboard shoulder main groove, an inboard shoulder main groove and a central main groove disposed therebetween. The land portions include an outboard central land portion and an inboard central land portion. The outboard central land portion is provided with first central sipes with a width of less than 2 mm, and is not provided with any grooves with a width equal to or more than 2 mm. The inboard central land portion is provided with second central sipes with a width of less than 2 mm, and is not provided with any grooves with a width equal to or more than 2 mm. The inboard central land portion is greater than the outboard central land portion in axial width.

Abstract: Provided is a tire including a tread portion. The tread portion includes two circumferential grooves and three land portions. The three land portions include a crown land portion disposed on a tire equator, and two shoulder land portions including tread contact ends. At least one of the shoulder land portions includes a plurality of main inclined grooves and a plurality of subsidiary inclined grooves. The main inclined grooves have tire-axially inner ends ending in the shoulder land portions and tire-axially outer ends disposed outwardly of the tread contact ends Te in the tire axial direction. The subsidiary inclined grooves have tire-axially inner ends ending in the shoulder land portions and tire-axially outer ends ending in the shoulder land portions.

Abstract: A tire includes having a tread portion that has three land portions defined by two crown main grooves that continuously extend in a tire circumferential direction and that are arranged across a tire equator. The three land portions include two shoulder land portions. At least one of the shoulder land portions includes a plurality of main inclined grooves that extend so as to be inclined. At least one of the main inclined grooves has an inner end and an outer end. The main inclined groove has a steeply-inclined portion that extends so as to be inclined from the inner end toward a tread end, and a gently-inclined portion that extends across the tread end from the outer end at an angle, relative to an tire axial direction, which is less than an angle of the steeply-inclined portion relative thereto. A length of the steeply-inclined portion is greater than a length of the gently-inclined portion.
