TYRE
FIG1 is a side view of a tyre according to a first embodiment of the disclosure
FIG1 illustrates a side view of a tyre 1 according to a first embodiment of the disclosure. The tyre 1 according to the present disclosure can be used for various kinds of tyres, e.g., pneumatic tyres for passenger car and heavy-duty vehicle, and non-pneumatic tyres that can support the tyre load by structural members without being inflated with a pressurized air. As illustrated in FIG1, the tyre 1 according to the first embodiment includes a tread portion 2 with a tread surface 2a provided with grooves 3. Preferably, at least one of the grooves 3, at least partially, includes a widening-width portion 3A.

['1. A tyre (1, 31) comprising: a tread portion (2, 32) comprising a tread surface (2a) provided with grooves (3, 13, 23, 33, 50); at least one of the grooves (3, 13, 23, 33, 50) comprising a widening-width portion (3A, 13A, 23A, 60) at least partially; the widening-width portion (3A, 13A, 23A, 60) comprising a first groove portion (4, 14, 24, 61) extending inwardly in a tyre radial direction from the tread surface (2a), and a second groove portion (5, 15, 25, 62) located inwardly in the tyre radial direction of the first groove portion (4, 14, 24, 61) and having a groove (W2, W12, W22, W41) width greater than that (W1, W11, W21, W40) of the first groove portion (4, 14, 24, 61), and the tread portion (2, 32) comprising a first shoulder land portion (37) having a first tread edge (T1), characterized in that the first shoulder land portion (37) is provided with first shoulder lateral grooves (50) extending inwardly in a tyre axial direction from the first tread edge (T1) and terminating within the first shoulder land portion (37), and the grooves (3, 13, 23, 33, 50) are the first shoulder lateral grooves (50), the tread portion (2, 32) has a designated mounting direction to a vehicle, and the first tread edge (T1) is located on a side away from the center of a vehicle body when the tyre (1, 31) is mounted to a vehicle, wherein the first tread edge (T1) is defined as one of axially outermost edges of the ground contacting patch of the tread portion which occurs under normal state with a standard tyre load when the camber angle of the tyre is zero.']
