How can we be sure that our tyres are suited to the suspension design of our chosen vehicle and vice-versa?
Introduction
This document presents a sizeable amount of tyre data collected by the author from different manufacturer sources. Most tyres are for racing purposes.
The data is useful for the creation of tyre models for simulation purposes in software such as ChassisSim, Pi Sim, Bosch Lapsim, Datas Racesim and many others.
The data is also useful for teams and manufacturers because in essence, the chassis/suspension design has to be done around the tyres: the 4 contact patches are the only thing connecting the car to the asphalt.
Rolling resistance
Rolling resistance is a very useful value for longitudinal dynamics calculations. Fortunately it does not have as large an effect as aerodynamic resistance.
A comprehensive study has been carried out by Chalmers University (Sweden) showing that in most modern tyres the coefficient can be as low as 0.0085 at speeds of 80 km/h. The coefficient is multiplied by vehicle mass and 9.81 (g) to obtain a force in Newtons: Tyre Rolling Resistance - Chalmers University
