Abstract: A tyre comprises a tread portion comprising a first tread edge and a second tread edge, and the tread portion is provided with a plurality of oblique grooves. The plurality of the oblique grooves includes a first oblique groove and a second oblique groove. Each of the first oblique grooves and the second oblique grooves has an open end and a terminating end, and a first steeply-inclined portion positioned on a side of the open end, a second steeply-inclined portion positioned on a side of the terminating end, and a mildly-inclined portion positioned between them. The second steeply-inclined portion includes a part in which an angle thereof with respect to a tyre circumferential direction is gradually decreased as it goes toward the terminating end.

Abstract: A pneumatic tire includes first and second tread patterns which are formed as substantially line symmetrical shape with respect to a tire equator and are shifted with respect to one another in a tire circumferential direction. Each of the first and second tread patterns is provided with lateral inclined grooves each extending axially inwardly from each tread edge to an axially inner end without reaching the tire equator. The tire is further provided with central connecting grooves each extend across the tire equator to connect lateral inclined grooves arranged on the first and second tread patterns. The central connecting grooves each include a first end and a second end such that the first end is located nearer to the tire equator than the second end and that a depth thereof decreases gradually from the first end to the second end.

Abstract: 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.

Abstract: Provided is a tire for winter of which on-snow performance can be improved without compromising anti-wandering performance. A tire for winter comprises a tread part The tread part is provided with: a plurality of first inclined major grooves extending at an incline from one tread end beyond a tire equator and ending without reaching another tread end; first inclined minor grooves provided between the first inclined major grooves; a plurality of second inclined major grooves extending at an incline from the other tread end, in a direction opposite the first inclined major grooves, beyond the tire equator and ending without reaching the one tread end; second inclined minor grooves provided between the second inclined major grooves; a plurality of first longitudinal grooves dividing first land parts; and a plurality of second longitudinal grooves dividing second land parts.

Abstract: A pneumatic tire includes a tread portion including a first tread pattern and a second tread pattern. The first tread pattern and the second pattern are formed as substantially symmetrical design to the tire equator and arranged such that pattern phases thereof are shifted one another in a circumferential direction of the tire. Each of the first tread pattern and the second tread pattern is provided with lateral inclined grooves each extending axially inwardly with an inclination from a tread edge to an axially inner end located near the tire equator, an inner connecting groove connecting between a pair of circumferentially adjacent lateral inclined grooves, and an outer connecting groove connecting between a pair of circumferentially adjacent lateral inclined grooves. A central connecting grooves is arranged to connect between a pair of axially adjacent lateral inclined grooves.
