A tyre for a vehicle wheel includes a carcass structure, a belt structure, a tread band, and at least one pair of sidewalls. The carcass structure includes at least one circumferential centering ridge jutting out from a crown portion of the carcass structure. Each bead of the tyre includes a rest surface defining, in a direction away from an equatorial plane of the tyre, a profile converging toward the rotation axis of the tyre. A rim for a tyre includes a base body and two seats. Each seat defines an abutment surface facing radially away from a rotation axis of the rim and includes a frustoconical configuration converging away from a median diametrical plane of the rim. The base body further includes at least two opposite radial shoulders disposed to abut against the at least one centering ridge. A vehicle wheel, including the tyre and the rim, is also disclosed.
