摘要： There is provided a precure tread and a retreaded tire using same capable of enhancing the stiffness of the land portion and significantly reducing likelihood of peeling off from the base tire during traveling by optimizing the cross-section shape of the rear surface groove of the precure tread, while maintaining the wet performance from the beginning to the end of wear life.A precure tread 1 has a circumferential groove 2 extending in a circumferential direction of a tire on a front surface which is to be a ground contact surface of the tire and a rear surface groove 4 extending in the circumferential direction of the tire on a rear surface which is to be attached to a base tire 3, the rear surface groove appearing from a tread surface as wear of the tread surface is progressed. Such rear surface groove 4 has a generally trapezoidal shape, as viewed in a cross-section in the width direction of the tire, and a width of the rear surface groove is constant or tapered from a bottom 5 to an opening 6 of the groove. Such precure tread is used to form a retreaded tire.

摘要： The present invention has an object to improve snow/ice performance, wet performance, and wear resistance of a pneumatic tire. The present invention provides a pneumatic tire which includes, in a tread, at least two circumferential grooves extending along a tire circumferential direction, a plurality of lug grooves extending in a direction crossing the circumferential grooves, and a plurality of blocks (30, 32) sectioned by the circumferential grooves and the lug grooves, wherein each of the blocks (30, 32) has a circumferential sipe (40, 46) connecting the lug grooves to each other formed on both sides of the circumferential sipe in the tire circumferential direction, and two lateral sipes (42, 48) extending from the circumferential sipe (40, 46) to a block end in a tire width direction, and the circumferential sipe (40, 46) extends so as to change the direction thereof at least once. With this structure, high performance of traction and braking on snowy and icy road surfaces and wet road surfaces can be obtained. Further, rigidity of the blocks at the time of ground contact, and thus wear resistance of the blocks can be improved.
