1. A method of preparing a tire, the method comprising steps of:
(i) providing a cured tire, the cured tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an innerliner layer disposed interior to the carcass layer;
(ii) directly applying an air barrier composition, which is distinct from the innerliner layer, to at least a portion of the innerliner layer of the cured tire to thereby form an air barrier layer, where the air barrier layer is in a cured state;
(iii) providing a dampening member as a pre-formed element; and
(iv) directly applying the dampening member as the pre-formed element to the air barrier layer in the cured state, such that the dampening member is not co-cured with the air barrier layer in the cured state, without any intervening layer between the dampening member and the air barrier layer.
