Abstract: Provided are: a tire reinforcement member having an improved durability; and a tire whose weight is reduced and durability is improved by using the tire reinforcement member.The tire reinforcement member is a tire reinforcement member 1 formed by winding a rubber strip 2 at an inclination with respect to the longitudinal direction of the member without any gaps while folding at width direction ends of the member, the rubber strip 2 being obtained by rubber-coating one reinforcing cord or a plurality of paralleled reinforcing cords. The rubber strip 2 substantially forms two reinforcing layers having different inclination directions. At a folding part T closest to a winding finish end 2e of the rubber strip 2, the rubber strip 2 is passed under an already wound rubber strip 2A and then folded, the already wound rubber strip 2A has been wound previous to the rubber strip 2 in an inclination direction different from that of the rubber strip 2.

Abstract: A tire comprises a crown zone comprising a crown reinforcement surmounted radially on the outside by a tread formed from at least one material that is not a conductor of electricity, the crown reinforcement comprising a plurality of layers superposed on one another, each layer of the crown reinforcement comprising two ends in the circumferential direction, these two ends being joined together in an abutment region, the tread comprising a weld region circumferentially offset by an angle of 180 degrees with respect to the region at which the radially outermost layer of the crown reinforcement is superposed. The tire comprises at least one conducting strip positioned between the tread and the crown reinforcement and located circumferentially as to be positioned at equal angular distances between the tread weld region and the region at which the radially outermost reinforcing layer is butted together, these two regions being diametrically opposite.
