Adapter for rolling assembly comprising tire and rim to provide the connection therebetween. The adapter has axially inner end with inner reinforcing element, axially outer end with outer reinforcing element, and a body. The outer reinforcing element, axially outside of bearing face (), is a bead wire made of three layers () of metal threads and concentric. First layer () includes metal thread of diameter D, 0.8≤D≤5 mm, second layer () has metal thread of diameter D, D≤1.4×D, and wound in a helix at angle A, 2°≤A≤10°, and third layer () has metal thread of diameter D and wound in a helix around second layer () at angle A, 2°≤A≤10°, and of opposite sign to A 1. An adapter for a rolling assembly having an axis of rotation , the rolling assembly comprising a tire having two beads , a rim having two rim bead seats , for each bead , the said adapter providing the connection between the bead and the rim , the said adapter comprising:an axially inner end comprising an inner reinforcing element and adapted to be mounted on a rim bead seat;an axially outer end comprising an outer reinforcing element and adapted to come into contact, via a substantially radial axially inner face, or bearing face, with a bead;a body connecting the axially outer end to the axially inner end so as to form a single piece, and comprising at least one main reinforcement providing the connection between the outer reinforcing element and the inner reinforcing element, and comprising a substantially axial adapter seat adapted to come into contact with a bead,{'b': 1', '2', '1', '2', '3', '3', '2, 'wherein the outer reinforcing element is wholly axially on the outside of the bearing face, wherein the outer reinforcing element is an annular structure, referred to as a bead wire, having a mean line and comprised of a stack of at least three layers comprised of metal threads and concentric with respect to the mean line, wherein a first layer or core comprises at least one metal thread having a diameter D ...
