Tyre for motor vehicles

A tyre for motor vehicles, having a tread band and comprising an annular central portion astride an equatorial plane of the tyre, two first annular side portions arranged on axially opposite sides with respect to the annular central portion and two second annular side portions each arranged between the annular central portion and a respective first annular side portion, the tread band having at least one module replicated along a circumferential direction of the tyre and comprising:

• at least two first grooves inclined with respect to the equatorial plane and each extending on a respective second annular side portion up to reaching a respective first annular side portion;
• at least two second grooves inclined with respect to the equatorial plane and spaced from said at least two first grooves in the circumferential direction, each of said at least two second grooves extending only on a respective second annular side portion and up to an axially outer portion of said second annular side portion;
• and
• at least two third grooves inclined with respect to the equatorial plane and arranged, along the circumferential direction, on the opposite side of said at least two first grooves with respect to said at least two second grooves, each of said at least two third grooves extending on a respective second annular side portion and on a respective first annular side portion, an extension on the second annular side portion being shorter than an extension on the first annular side portion.
