What determines when tire marks are made in a simulation? Is there a way to turn them off?
By default, tire marks appear when the ratio of total tire force to adhesion exceeds 95% of dynamic loading at the contact patch. As of the Spring 2026 Software Update, in Virtual CRASH 6, this threshold is adjustable via the "visibility threshold" slider (note: values up to 200% can be entered manually in the input field). Users can also opt to have tire marks appear when the ratio exceeds the threshold of static loading at the contact patch. In the example below, the red vehicle uses a dynamic loading threshold while the blue vehicle uses static loading.
If you do not wish the automatically generated tire marks to appear, or you wish to draw your own, the automatically generated tire marks are easy to disable in Virtual CRASH. Simply select your vehicle and go to the “tire marks” menu in the left side control panel. Use the color drop down menu, and set to full transparency.
Below we see a simulation of a car entering a yaw maneuver with (right) and without (left) visible tire marks.
