Vehicle rim for mounting of a tire, comprising: an axially central part (20) comprising a disc; two lateral parts (31, 32), at least one of the lateral parts being separate from the axially central part, each of the lateral parts having a rim seat to receive a bead of a tire, the axially central part and the two lateral parts being made from a rigid matrix; an intermediate part (41, 42) that forms the only mechanical link between the axially central part and each lateral part that is separate from the axially central part, this intermediate part being made of a flexible matrix, the Young's modulus of uniaxial extension of the flexible matrix being greater than and equal to 50 MPa and less than or equal to 400 MPa; wherein the Young's modulus of uniaxial extension of the rigid matrix is greater than or equal to 5 GPa.
