O processo inclui as etapas de montar um pano-forro interno em um tambor de construção de pneumático, extrusão de uma composição selante em tiras tendo costados cuneiformes, cortar a tira a um comprimento desejado, montar o selante no pano-forro interno, e estratificar um ou mais componentes do pneumático sobre o selante. A method for making a tire (2) with a built in sealant (7) is provided. The method includes the steps of mounting an inner liner (6) onto a tire building drum and extruding a sealant composition into at least one strip (7). It further includes (1) cutting the strip (7) to a desired length, mounting the at least one strip (7) over the inner liner (6), and layering a tire component (9) over the at least one strip (7) mounted over the inner liner (6); or (2) helically winding the at least one strip (7) over the inner liner (6), and layering a tire component (9) over the at least one strip (7) mounted over the inner liner (6). There is also a tire provided having a built-in sealant (7) being arranged over an inner liner (6) of the tire, the built-in sealant (7) being covered by a barrier layer (9) or a carcass which encloses the built-in sealant together with the inner liner (6).
