The recessed region has a vertical face that forms a first edge, and has a planar base that intersects the opening sidewall of the sipe. The planar base and the opening sidewall of the sipe forming a second edge at which the angle between the planar base and the opening sidewall is not greater than 90. Difference in height in the vertical direction of the first edge and the second edge is greater than or equal to 0.5 mm but is less than or equal to 1.5 mm. Distances to the first edge and the second edge in the width direction of the sipe are not less than 1.5 mm.

A pneumatic tire 1 comprises a tread portion. The tread portion 2 is provided with a plurality of oblique main grooves 3 and oblique land regions 4. The oblique land regions 4 each divided by a first vertical groove 6 into a shoulder block 10 and a middle block 11 disposed axially inside thereof. The shoulder block is provided with a plurality of transverse sipes 15 whose angles with respect to the tire axial direction are less than 45 degrees. The middle block 11 is provided with a plurality of vertical sipes 16 whose angles with respect to the tire circumferential direction is less than 45 degrees.

A pneumatic tire provided with, in a tread surface, at least two main circumferential grooves, and a first land portion defined by the two main grooves, wherein in the first land portion, the followings are disposed: a first inclined groove; inclining relative to a tire width direction, and having one end portion opening in the main groove on one side adjacent to the first land portion and the other end portion terminating within the first land portion, and a first notched portion; having one end in a tire width direction as a tip positioned at an endmost, in a tire width direction, of the other end portion of the first inclined groove and the other end in a tire width direction opening in the main groove on the other side adjacent to the first land portion.

Provided is a tire set for three-wheeled vehicles, the tire set being to be mounted on a three-wheeled vehicle of a type that makes a turn by tilting tires during cornering, and the tire set exhibiting excellent ride comfort, especially during high-speed running, and excellent handling performance and lightness in weight. The tire set for three-wheeled vehicles is to be mounted on a three-wheeled vehicle that is configured with two front wheels and one rear wheel or with one front wheel and two rear wheels and includes a mechanism for tilting tires during cornering. A two-wheel side tire to be mounted on the two-wheel side has a tire diameter smaller than a tire diameter of a one-wheel side tire to be mounted on the one-wheel side, and the two-wheel side tire includes a lateral groove (1) extending across the tire equator on a tread portion.

A car tyre having a tread that extends in axial direction for a width the tread including a central portion arranged across an equatorial plane, and two lateral portions opposed with respect to the central portion. The central portion is separated from the lateral portions of the tread by two circumferential grooves. The circumferential grooves have a width greater than about 6 mm. The central portion extends in axial direction for a width less than 20% of the width of the tread and includes a plurality of first sipes. Each lateral portion has a width greater than 30% of the width of the tread, and each lateral portion includes, furthermore, a plurality of transversal grooves. The transversal grooves of a lateral portion include at least a first inclined length that extends from a zone proximal to the respective circumferential grooves, moving away from the equatorial plane. The first inclined length has an inclination 60 with respect to equatorial plane. Each lateral portion includes a plurality of sipes. The density of the sipes decreases moving away from the equatorial plane.

A pneumatic tire includes a tread; sidewalls; and beads. Lug grooves are formed in the tread inclining symmetrically about an equator, an inclination angle of the lug grooves relative to the lateral direction being 1545. A width W1 of the lug grooves at the tread edge and an interval W2 between the lug grooves at the tread edge satisfying 0.7W1/W21.5. Shoulder grooves connecting lug grooves are inclined in an opposite direction to the lug grooves have an inclination angle relative to the lug grooves being 80100, a center position of the shoulder grooves being 15% to 35% of tread width TW from the equator. An area A1 of the shoulder grooves and an area A2 of shoulder blocks satisfy 0.2A1/A20.6. A groove area ratio of the tread is 0.4 to 0.7.
