Abstract: The present invention relates to a tire comprising a means for indicating the position of a tire among the set of tires of a vehicle. The means is a button, which is fitted in a recess made in the center of a pattern which illustrates the tire positions of the vehicle, so that the position of this particular tire among the set of tires of the vehicle can be indicated unambiguously by turning the button by means of the pattern on the button. The button has a groove and/or an embossment for turning the button by means of a screwdriver with a chisel head, a coin or a pair of pliers, for instance.

Abstract: The invention relates to a vehicle tire (50) comprising a tire carcass (51) and side walls (53); a layer or layers of rubber forming a tire tread (56) on top of the carcass; a tread pattern comprising a plurality of blocks (11) separated by grooves (22). There are anti-skid stud holes (12) in the blocks, said anti-skid stud holes having a total depth within said tread rubber layer and having a generally circular or oval cross-sectional form. Lamellar anti-skid studs (1) are inserted in the stud holes, the ratio of the total thickness (D1) of said lamellar studs to the width (L) of said lamellar studs in the orientation of the tread surface (20) being at maximum one-third. The diameter or respectively the main dimension of said circular/oval stud holes (12) is substantially smaller than the width (L) of the inserted lamellar studs.

Abstract: The invention relates to pattern blocks in the tread of a vehicle tire, the tread comprising the tread layer (20) on the tire carcass (25) and on that pattern blocks (1) separated from each other by wider grooves (21). At least part of these pattern blocks comprise fine slits (2), which are substantially narrower than the grooves, each slit comprising within the area (A1) of the pattern block at least one bend (5) or at least one end (4). Two adjacent slits (2) form surface tear points (10), each of which is formed of: webs (3a, 3b) between at least one end (4) of one slit and at least one second slit or its end; or webs (3c, 3d) between the bend of one slit and one second slit or its bend (5). The web width (W2) of the webs is at most five times the slit width (W2), and the adjacent slits restrict between their mutual webs (3a-3d) between them nubs (8) inside the pattern block.
