Comparison of Tire Behavior using Vehicle Dynamic Simulation

The objective of this paper is to present a work conducted aiming to compare the behavior of different types of tires, using Simulations.

During the development phase of a new vehicle, it is very convenient to have any prediction of tire behavior, to make earlier design decisions. This paper describes the use of Vehicle Dynamics Simulation as a tool to make a comparison of different tire sizes and constructions in the same vehicle. In this particular case we will present the result in terms of steering and handling of three different tires, with a combination of two different constructions (same basic dimensions) and two different tire sizes (same basic tire design family), in the same vehicle.

Several maneuvers were simulated and all result parameters were analyzed aiming to define the best compromise in terms of vehicle overall performance and safety. The final results were used as a guide to drive future design activities in this particular vehicle.
