Barcelona - tyre dynamics and deformation 05 May 2005

The car is set up with a camber angle so that the tyre becomes perfectly vertical when cornering, maximising its contact patch. This angle change is due to the chassis' roll and yaw movement - it rotates around the centre of roll (yellow and black dot). Furthermore, the lateral forces on the car when cornering (large red arrow) make it want to slide on its tyres. This is countered by the controlled deformation of the tyre shoulder (large yellow dot).
