  • Publication number: 20140130948
    Abstract: A tyre includes a tread with at most 30 channels distributed substantially evenly circumferentially about the tyre. Each channel is arranged so that, beyond a predetermined wear threshold, the channel satisfies the following conditions: (A) the channel opens into a tread pattern element of the tyre, and (B) the channel includes a mouth opening radially to outside of the tyre and is delimited by at least two edge corners that come into contact with a ground surface as the edge corners pass through a contact patch in which the tyre is in contact with the ground surface, in which a circumferential distance separating the edge corners from one another is greater than or equal to 2 mm, and preferably is greater than or equal to 4 mm. Before the predetermined wear threshold is reached, at least one of the conditions (A) and (B) is not met.

  • Publication number: 20140124108
    Abstract: A tyre includes two sets of acoustic (sonic) wear indicators associated with two wear thresholds. Noise is generated when each wear threshold is exceeded. Each wear indicator of each set of wear indicators is axially aligned with each other wear indicator of that set of wear indicators. A number of sets of wear indicators associated with each wear threshold is different from a number of sets of wear indicators associated with each other wear threshold. The sets of wear indicators associated with each wear threshold are evenly distributed circumferentially about the tyre. Each wear indicator is formed of a projection of rubber extending from a bottom portion of a circumferential groove of the tyre.

    Abstract: The invention relates to a tire tread for a passenger vehicle comprising a tread surface designed to come into contact with a ground when this tire is running. The tread comprises at least one internal cavity of elongate overall shape with a total length LC and width WC and a sipe less than 2 mm wide beginning partly or totally on the cavity. The sipe extends the cavity over the whole of the length LC while extending radially outwards in order to emerge on the tread surface. The cavity comprises a bottom and two lateral walls surrounding this bottom and extending in the length LC of the cavity. The bottom comprises a message intended for an observer of the tire and the message is at a distance from at least one lateral wall of the cavity, the distance between the message and the said lateral wall being at least equal to 5% of the width WC of the cavity.

    Abstract: A tread wear indicator may be molded into the shoulder region of a tire tread and may have three symbols. Two of the symbols may be alphanumeric characters and the third symbol may surround the two symbols. All three symbols may be visible prior to wearing the tread. After the tread has been worn a first amount, the first symbol may be invisible and the second and third symbols may be visible to indicate to the user that a new tire will soon be required. After the tread has been worn a second amount, the first and second symbols may be invisible and the third symbol may be visible to indicate to the user that a new tire is required immediately.

  • Publication number: 20120273102
    Abstract: A tyre for a vehicle has at least two predetermined radial wear thresholds. Beyond each threshold, a tread of the tyre is configured in such a way that the tread includes at least one set of at least one cavity, known as a “sounding” cavity, associated with that threshold. If a set includes a plurality of cavities, each cavity of the set is substantially aligned axially with each other cavity of the set. A number of the set(s) of cavity/cavities associated with each threshold is different from a number of the set(s) of cavity/cavities associated with each other threshold. The sets of sounding cavities are arranged in such a way that, beyond each threshold, the set(s) of sounding cavity/cavities associated with that threshold are evenly circumferentially distributed about the tyre.
