Abstract
The invention is directed to a tire comprising an innerliner including a recess with a depth within a range of 20 μm to 3000 μm and a stepped sidewall, wherein at least one step of the recess' sidewall includes a height within a range of 5 μm to 1500 μm. Furthermore, the invention is directed to a method of processing a tire including an inner surface, wherein the method comprises creating a stepped recess in an area of the inner surface by removing a first thickness of elastomer composition in a first subarea, removing a second thickness of elastomer composition in a second subarea, wherein the second subarea at least partially overlaps with the first subarea so that a third thickness of elastomer composition is removed in an overlapping zone of the first subarea and the second subarea.
