Tire Pressure Loss and Intracarcass Pressure Modeling

Abstract

Abstract The inflation pressure loss and carcass pressure build-up (intracarcass pressure or ICP) of tubeless tires can be predicted with a simple theoretical model. Tire construction and relative air permeabilities of the main tire components are significant factors in the pressure loss and ICP. Highly impermeable liners play a major role in obtaining optimum results. Application of the model to recent European passenger tire surveys is shown.
