摘要： A pneumatic tire comprises: a carcass comprising a carcass main extending from a bead core in one of bead portions to a bead core in the other bead portion, and a pair of carcass turnups axially outside the carcass main; a tread rubber disposed in the tread portion; a sidewall rubber disposed in each of the sidewall portions; and a wing rubber interposed between the tread rubber and sidewall rubber. Each of the carcass turnups extends from the axially outside of the bead core to a point in the sidewall portion. While extending from the axially outside of the bead core to the point in the sidewall portion, the carcass turnup approaches the carcass main and adjoins the carcass main from a first radial height to a second radial height and then separates from the carcass main from said second radial height so as to form a separating part. The wing rubber has a JIS type-A durometer hardness of from 45 to 60 degrees, and a radially inner part of the wing rubber is inserted between said separating part and the carcass main.

摘要： A tyre for vehicles includes a carcass structure, a belt structure, and a tread. The tread includes a row of central blocks and a row of intermediate blocks arranged on each side of an equatorial plane of the tyre between a central longitudinal groove formed astride the equatorial plane and a pair of longitudinal lateral grooves. The blocks of the central rows are separated from the blocks of the intermediate rows by circumferential sipes and are circumferentially staggered by a first predetermined quantity relative to the blocks of the intermediate rows. Also, the blocks of the central rows arranged on a first side of the equatorial plane of the tyre are circumferentially staggered by a second predetermined quantity relative to the blocks of the central rows on a second side of the equatorial plane of the tyre.
