Pretty old trick actually. But overlooked. Im shocked there is no thread about it yet. 1. At the main screen, go to the car settings. 2. Make sure one of your A,B,C setup has racing/sports/comfort tires installed. After that change to something else beside that. 3. Go to the dirt/snow track. 4. Go to car settings again. Then change the setup to that which contains racing/sports/comfort tires. 5. Go race/drive! This can be applied backwards a.k.a putting snow/dirt tires on the road tracks. - The handling feels like what happen when you drive on the gravel on the road tracks. - For the vice nersa, there is some artificial grip made specifically for those dirt/snow tires. - Some cars has the rim changed. Some others does not. Pitcures: Snow tire on road with 15 Anniversary car: Dirt tire on road with base model: Racing tire on dirt with base model: Snow tire on the road with base model: Important note: After changing car settings, DO NOT click the "driving options"! It will revert to the correct tires. If you want to change driving options please do it before doing this glitch.
