A tire has a coating with a quadlayer or multiple quadlayers, and a method produces the same. In an embodiment, the method for coating a rubber substrate includes exposing the rubber substrate to a first cationic solution to produce a first cationic layer on the rubber substrate. The method also includes exposing the first cationic layer to a first anionic solution to produce a first anionic layer on the first cationic layer. In addition, the method includes exposing the first anionic layer to a second cationic solution to produce a second cationic layer on the first anionic layer. The method further includes exposing the second cationic layer to a second anionic solution to produce a second anionic layer on the second cationic layer. A quadlayer includes the first cationic layer, the first anionic layer, the second cationic layer, and the second anionic layer. The coating includes the quadlayer.
