In the tasks of modeling the motion stability, controllability and braking dynamics of cars and buses, information is required on the car tires contact length with the road surface. The car tires contact length is usually calculated from geometrical considerations (using the Hedekel formula). In this case, the experimental data of this value turn out to be less than the calculated ones due to the deformation features of the car tires. To account for this reduction in the contact patch length, the authors developed a general method for determining the correction coefficient. Previously, they developed a similar method for low-profile radial passenger car tires. Now it is valid for all passenger and truck tires. This will allow calculating the car tires contact length more correctly.
