This paper presents a novel numerical tool for predicting tire/road friction by modeling the tire/road contact dynamics. Incorporating a comprehensive range of influential parameters related to tire properties, road conditions, contaminants, and contact operating conditions, the tool offers a holistic approach to friction estimation. Validation of the tool is achieved through braking tests conducted on a passenger car across a spectrum of speeds and diverse wet road surfaces exhibiting varying textures. The tool effectively ranks the friction coefficients associated with ABS (peak friction) and locked-wheel (sliding friction) conditions on these varied road surfaces, affirming its accuracy and utility in assessing tire/road interactions.
