Abstract
Aspects of the present invention relate to methods for characterizing a multi-layered tire tread. In one example, a method comprises providing a first rubber composition having a first refractive index and providing a second rubber composition having a second refractive index. The method further comprises determining a difference between the first refractive index and the second refractive index and comparing the difference to a threshold refractive index. In addition, the method comprises adding a refractive index modifier to the first rubber composition and/or second rubber composition in case the comparison provides that the difference is lower than the threshold refractive index, so that the difference is greater than, or equal to, the threshold refractive index.
