Increased friction between the tire and the riding surface is the goal of nearly every tire manufacturer. You could easily coat your tire in oil to accomplish the lower friction you are talking about. WebDec 25, 2024 · f – Coefficient of friction between the tires and the road. It is assumed to be 0.7 on a dry road and between 0.3 and 0.4 on a wet road. This formula is taken from the book "A Policy on Geometric Design of Highways and Streets". It is commonly used in road design for establishing the minimum stopping sight distance required on a given road. peter lohmeyer wikipedia https://jacobullrich.com
