This article consists analyze of car stability, of the forces that are pushing the tires, also what is the roughness of the road‘s surface. The safety of the roads is influenced by alot of other factors. One of them is the surface of the road, it‘s smooth lines. Big amount of the heavy trucks and cars are deforming the surface and because of this problem there are a lot of roads roughness. This article also analyze how the roughness of the road influence the stability of the car. There is given the vehicle 3D model, which interact with rough road‘s surface. Also there is accomplished mathematical model, during that model there was determinated, what kind of forces are pushing the tires while going on the rough road on 60 km/h speed and the roughness of the road is 0,05m. All the results are given on the diagrams.
