    Abstract: A racing tire coated with a composition that contains rubber extracted from used tires dispersed in a combination solvent has increased traction, pliability and service length over untreated racing tires. The extracted rubber can be natural rubber, synthetic rubber, or a mixture thereof, while the solvent includes a major amount of a mixed hydrocarbon petroleum distillate, and minor amounts of dimethyl ketone and methyl salicylate.

    Abstract: According to the invention, there is provided a pneumatic tire with a 3D kerf, including: one or more 3D kerfs; and a tire having a tread and a shoulder formed at a side surface of the tread. The tread has: one or more grooves that are sunken toward a center of the tread and are formed in a circumferential direction of the tire; one or more kerf grooves that are sunken toward the center of the tread and are formed in a central axis direction of the tire; and one or more blocks which are divided by the one or more grooves and the one or more kerf grooves, respectively. The one or more 3D kerfs come into close contact with and are fixed between the one or more blocks, respectively, as being inserted into the one or more kerf grooves, respectively.

    Abstract: A tire (1) comprises two beads (4), two sidewalls (3) connected to the beads and a crown (2) connected to the ends of the two sidewalls, the crown comprising a crown reinforcement (6) and a tread (5) radially outside the crown reinforcement (6), said tread (7) comprising a plurality of tread pattern blocks (71), at least two radially superposed layers: a sublayer (7S) covering the crown reinforcement (6), and a main layer (7P) radially above the crown reinforcement (6), the sublayer comprising a plurality of circumferential reinforcing elements (73) being formed of a rubber compound having greater stiffness than the stiffness of the rubber compound of the rest of the sublayer, the circumferential reinforcing elements (73) extending radially from the radially exterior surface of said crown reinforcement (6) in the direction of the interface between the sublayer (7S) and the main layer (7P), said circumferential reinforcing elements having an axial width which decreases gradually with increasing radial proximity to the outside.
