摘要： Airplane tire tread (2), having an axial width L, comprises a middle part (3) having an axial width LC between 50% and 80% of L and composed of a middle rubber composition, and two lateral parts (41, 42), positioned axially on either side of middle part (3), each having an axial width (LS1, LS2) between 10% and 25% of L and each composed of a lateral rubber composition. The middle rubber composition comprises at least 50 phr of a first middle part diene elastomer (“FMPDE”), at most 70 phr of a middle part reinforcing filler (“MPRF”) and a crosslinking system. FMPDE is a terpolymer of ethylene, of an α-olefin and of a non-conjugated diene. The FLPDE lateral rubber composition of each lateral part comprises at least 50 phr of a first lateral part diene elastomer, a lateral part reinforcing filler content at least equal to the MPRF and a crosslinking system. The FLPDE is a terpolymer of ethylene, of an α-olefin and of a non-conjugated diene.

摘要： A tire has a cap rubber formed of a nonconductive rubber and forms a ground surface, and a conductive portion provided in at least one side end portion of a pair of side end portions in both ends in a tire width direction. The conductive portion is formed of a conductive rubber, and reaches a side surface of the cap rubber from the ground surface through an inner portion of the cap rubber. The conductive portion is the smallest in thickness in the ground surface, is relatively large in thickness in the side surface of the cap rubber, is gradually increased in thickness from the ground surface to the side surface of the cap rubber, and is formed into a trumpet shape which is curved into an inner side in a tire width direction and an inner side in a radial direction, in a tire meridian cross section.

摘要： The invention relates to a tire having a rubber tread of a circumferentially zoned tread. The tread zones are comprised of three circumferential load bearing zones, with each zone containing a portion of the running surface of the tread, comprised of a silica-rich intermedial rubber zone positioned between and extending beneath two carbon black-rich lateral tread zones. The tread configuration contains an underlying carbon black-rich base rubber layer. The intermedial and stratified lateral zones are comprised of rubber compositions having differentiated rebound physical properties. A path of least electrical resistance extends from a lateral carbon black-rich rubber tread zone to the carbon black-rich tread base layer by an extension of a lateral tread zone or by an intermediate carbon black-rich rubber bridge.

摘要： Tread rubber forms a ground contact surface. When the ground contact surface is divided into two parts: a mounting inner side and a mounting outer side, the tread rubber has an inner cap part that forms an inner ground contact surface and is produced from non-conductive rubber, and an outer cap part that forms an outer ground contact surface. The inner cap part has a branched conductive part that is formed from conductive rubber ranging from the ground contact surface of a mounting outer end of the inner cap part to the side surface or bottom surface of a mounting inner end while branching off at a plurality of positions. The outer cap part does not have branched conductive rubber. The branched conductive part is formed from the conductive rubber with a rubber hardness different from that of the non-conductive rubber that forms the inner cap part.

摘要： The invention relates to a tire with circumferentially zoned tread including peripheral sidewall extensions. The tread zones are comprised of three circumferential load bearing zones, with each zone containing a portion of the running surface of the tread, comprised of an intermedial rubber zone positioned between and extending beneath two stratified lateral tread rubber zones and, in addition, peripheral sidewall extensions. The tread configuration contains a carbon black reinforced tread base rubber layer underlying the intermedial tread rubber zone. The lateral tread rubber zones are therefore spaced apart from each other with the intermedial tread zone therebetween and also at least partially spaced apart from the tread base rubber layer with the intermedial tread zone therebetween. The tread includes a peripheral carbon black reinforced rubber layer as an extension of the tire sidewall which extends radially outward from the outer tire sidewall to thereby join a portion of a lateral tread zone which may extend to and include a portion of the running surface of the tread.

摘要： In a motorcycle tire, since a reinforcement cord that constitutes a belt layer (24) is constituted by a cord having a low modulus of elasticity (a tensile force upon 1% elongation is 15 N or less), a shearing force in a circumferential direction of a tread (26) is decreased. As a result, a value of frictional energy is decreased, and abrasion resistance of the tread (26) (a center section (27)) is improved. Moreover, since tan δ of shoulder sections (28) is larger than tan δ of the center section (27), a grip limit in the shoulder sections (28) that are grounded upon turning is increased, and turning performance is improved.
