In curves, the following factors can lead to skidding: 1. excessive speed; 2. wet or icy roads; 3. strong braking. In turns, much of the stiction forces are needed for the cornering forces that hold the vehicle in the lane. If you brake too much, the stiction is instead used largely for the transmission of the braking force. As a result, the cornering forces are too low to counteract the centrifugal force, the same applies to excessive speed. On wet roads, a film of water between the road surface and the tire reduces grip and promotes skidding.
