摘要： The tread of a multipurpose tire includes a central region and first and second shoulder regions. Circumferential grooves separate the central and shoulder regions. The central region includes first and second rows of blocks. The first and second rows are arranged between an equatorial plane of the tire and either of the circumferential grooves. The first row is separated from the second row by first and second grooves extending in first and second oblique directions relative to the equatorial plane. The first oblique direction is substantially perpendicular to the second oblique direction. Each first groove is connected to two second grooves at essentially T-shaped junctions. At least two blocks of the first row are separated from each other by a third groove substantially parallel to the second oblique direction. The third groove is connected to a first groove at an end of the first groove nearest the equatorial plane.

摘要： A tread for motor-vehicle tyres has a raised pattern formed of a plurality of shaped blocks (7) distributed according to circumferential rows (3, 4, 5, 6) disposed parallelly in side by side relation. The number of the shaped blocks (7) arranged in each row gradually increases on passing from the equatorial plane (X-X) to the side edges (1a) of the tread (1). Thus a gradual increase in the longitudinal stiffness of the shaped blocks (7) is achieved on passing from the side edges (1a) of the tread (1) to the equatorial plane (X-X), which brings about a reduction in the mobility of said blocks on the imprinting area and a greater quietness of the tyre in use.

摘要： A tread pattern for motor-vehicle winter tyres has transverse grooves (2) symmetrically converging at the equatorial plane "X" of the tyre, ad a pair of circumferential grooves (3) respectively defined by oblique stretches (3a) having an orientation converging at the equatorial plane "X", in a direction opposite to the rolling direction "D" according to which the transverse grooves (2) converge. Grip hollows (6) of increasing width in a direction opposite to the rolling direction, are formed astride of each transverse groove (2), at two contiguous centre blocks (4). A central separation cut (7) between the centre blocks (4) defines therein separation walls (7a) arranged to come into mutual contact under the ground contacting area.
