Masayohi Nomura

A tire for two-wheeled motorized vehicle having tread connected by sidewalls to beads, each having circumferential reinforcing bead wire, each contacting a rim on which the tire is mounted, the tire has an indicator system of a plurality of cavities formed on tread surface, each cavity having maximum depth less than 1 mm and average width of less than 3 mm, and arranged in a plurality of circumferential sets of cavities) representing different camber angles of the tire, each circumferential set having plurality of cavities arranged in circular arc, wherein two adjacent cavities are spaced along circular arc by circumferential pitch (Pc) between 1 mm and 10 mm, the circumferential sets arranged in specific radial pattern defined by a radial pitch (Pr) corresponding to spacing in radial direction between circular arcs of two adjacent circumferential sets of cavities, the radial pitch (Pr) being between 1 mm and 10 mm.

Tire

The device for monitoring the wear of a tread during running comprises at least one internal cavity intended to form a void opening on to a tread surface after predefined partial wearing of the tread, this tread comprising a wear limit corresponding to a maximum thickness of wearable material, this device comprising a measurement well opening on to the tread surface, this measurement well having a bottom formed of a first part and of a second part which are offset from one another in the depth, these two parts of the bottom being situated at different distances with respect to the tread surface when new.

Tire wear monitoring device

The tread includes over at least a first axial part (M) at least one wavy groove in a first direction and wavy grooves in a second direction. The wavy grooves in the second direction are connected to the wavy groove in the first direction. Over at least a second axial part (B) of the tread, at least one wavy groove continuous in a third direction, and wavy grooves continue in a fourth direction. The wavy grooves in the fourth direction are connected to the wavy groove in the third direction. When new, the open parts of the first axial part (M) are connected to one another, and the open parts of the second axial part (B) are not connected with one another. Beyond a part-wear condition, the open parts of the second axial part (B) are connected to one another, and the open parts of the first axial part (M) are not connected with one another.

Evolving tread for a tire

Die () representing a tread pattern model for a tread of a tire to be molded, said die being made up of a die body () and at least one insert () attached to the body of said die, covering at least one of the surfaces of the grooves () in the body (), the insert having at least one substantially flat surface provided with textures.

Die having textured inserts for manufacturing a textured mould for moulding and vulcanizing tires

A tire () made of rubber material, comprising a tread (), said tread having a tread surface () intended to come into contact with a road surface when the tire is being driven on, this tread surface having, in cross section, a certain curvature. The tread surface () comprises, over at least 80% of its surface, a texture () contrasting with the rest of the tire, this texture () having a plurality of elements that protrude from or are recessed into the tread surface (), and each element extends perpendicularly (&#x3b8;=90&#xb0;)to the tread surface () along the curvature of this tread surface ().

Tire including a high-contrast texture on the tread surface

A tread for a heavy vehicle tire of total thickness PMU this tread when new having a tread surface is provided and disclosed herein. The tread includes at least one cut opening in the initial condition onto the tread surface, this cut being such that it includes an external part having the form of a groove in the main direction, this groove having a mean depth Pe less than 80% of the thickness PMU, an internal part forming the bottom of the cut, this internal part having the shape of a channel of mean width Le and mean height He, this channel being intended to form a new continuous groove when the part wear of the tread reaches at most 80% of the thickness PMU.
