The invention relates to a method of making a composite innerliner. A method for forming a tire having an innerliner is described. The method comprises the steps: forming a coextruded strip of a firstcompound and a second compound, wherein the first compound is an air impermeable compound, and the second compound is a crosslinkable diene rubber compound; and winding the coextruded strip onto a tire building drum while varying the ratio of the first compound to the second compound to form the innerliner as an inner liner layer of spirally wound coextruded strips. 本发明涉及一种制造复合内衬的方法。具体描述了一种用于形成具有复合内衬的轮胎的方法，其中，该方法包括以下步骤：形成第一胶料和第二胶料的共挤出条带，其中，第一胶料可以是不透气胶料，并且第二胶料是可交联的二烯橡胶胶料；将共挤出条带缠绕到轮胎成型鼓上，同时使第一胶料与第二胶料的比率变化，以形成螺旋地缠绕的共挤出条带的内衬层。
