Abstract

Surface texture is studied and interpreted through signal theory, fundamental, and empirical tests.
It affects many characteristics including rolling resistance, friction, noise, and hydroplaning.
These characteristics need to be predicted at the design stage because of the consequences on sustainability and safety.
In the light of the above, surface texture emerges as a pivotal set of indicators that poses at least two main issues: their predictability and their “power” to predict.
