TLDR
The Magic Formula model as mentioned in this paper provides a set of mathematical formulae from which the forces and moment acting from road to tyre can be calculated at longitudinal, lateral and camber slip conditions, which may occur simultaneously.Abstract:
An account is given of the latest version 3 of the Magic Formula tyre model. The model provides a set of mathematical formulae from which the forces and moment acting from road to tyre can be calculated at longitudinal, lateral and camber slip conditions, which may occur simultaneously. The model aims at an accurate description of measured steady-state tyre behaviour. The coefficients of the basic formula represent typifying quantities of the tyre characteristic. By selecting proper values, the characteristics for either side force, aligning torque or fore and aft force can be obtained. The new version of the model contains physically based formulations to avoid the introduction of correction factors. Double-sided, possibly non-symmetric pure slip curves are employed as the basis for combined slip calculations. Suggestions are given to estimate the driving part of the longitudinal slip curve and to represent the characteristic at rolling backwards.read more

A vision-based approach to wheel camber angle and tyre loaded radius measurement
TL;DR: In this paper, a vision-based method for direct camber determination has been developed and a measurement prototype has been designed, which is mainly aimed at giving accurate measurement Its precision is robust to the road's unevenness and the vehicle's velocity; the tyre loaded radius is determined at the same time.

Decrease in Ground-Run Distance of Small Airplanes by Applying Electrically-Driven Wheels
TL;DR: In this article, the ground-roll performance of an airplane driven by electrically-powered wheels was experimentally and computationally studied, and it was shown that the ground run distance of the wheel-driven aircraft was independent of the motor power when the motor capability exceeded the friction between tires and ground.

TL;DR: In this article, the Magic Formula Tyre Model is compared with the Monte Carlo version of the model and the comparison between the two versions shows that the latest version results in better fitting results especially for camber influences and (even more important) in an improvement on the fitting process.
